The transfer of the units determine the volume per unit weight is very easy, it all depends on the substance from which made the object. Help can come in the course of physics for grade 8 regular high schools.

Cubic meters (m3) are the standard system unit of volume. Therefore, the results of many measurements and calculations are often required to submit in cubic meters. If the source information is specified in the related non-si units (liters, cubic centimeters, etc.), to calculate cubic meters is not difficult. However, if other physical quantities (mass, area, length), it will take dopolnitelnaya information.

When working with small amounts of substances are often used as a unit of mass, as milligram (mg). A milligram is called a thousandth of a gram. that is, one gram contains one thousand milligrams. To convert grams to milligrams don't even need the calculator – it enough elementary knowledge of arithmetic.

Speed, time and distance is a physical quantity, interconnected process of movement. Distinguish between uniform and uniformly accelerated (daunosamine movement) of the body. In uniform motion the velocity of a body is constant and does not change over time. In uniformly accelerated motion the velocity of a body changes with time. Understand how to find each of the quantities, if known to the other two.

The standard unit of volume cubic meter is considered. However, in everyday life is often used and smaller non – si unit is the liter. Knowing the volume of material in litres, easily convert it to cubic meters and Vice versa. But when measuring the volume of gas, liters are generally used for liquefied natural gas, and cubic meters for a normal trunk.

Crystals are substances in which atoms or molecules form an ordered structure. The crystals are very common in nature, they often grow to very large sizes. But it is possible to grow crystal at home. This is enough of minimum resources.

In grams measured body mass in any physical state, in milliliters is the volume of the liquid. The mass of a substance depends on its density, which in turn depends on physico-chemical properties of substances and external conditions. We will understand how to align those physical quantities.

5% solution is a solution with a concentration of 5%. That is, the dry mass, in this case, potassium permanganate, should be 1/20 of the weight of the solution.

Smoke bombs many were interested in boys and quite young boys in the days of the Soviet Union. Checkers and still has not lost its relevance. By the way, smoke bombs are used not only by young hoodlums for their pranks, but the military and police and many other people. So serious guys need not simple checkers, and "color".

Suites and lumens are very often confused. These values are used to measure illuminance and luminous flux, respectively, and they need to distinguish. The luminous flux characterizes the light source and the light level – the state of the surface on which the light falls. For the measurement of light the measurement unit is Lux (LX), and for the characteristics of the light source is applied to the lumen (LM).

With the need to calculate the slope constantly faced by architects, designers, builders of roads and communication networks, as well as people of several other professions. On the earth's surface is very difficult to find a perfectly smooth area. Slope is expressed in degrees or percentage. The designation in degrees indicates the angle of curvature of the surface. But the bias can be represented in the form of the tangent of that angle multiplied by 100%.

Soda is a product that is easy to find in the kitchen locker of every housewife. But not everyone knows that soda is the universal medicine for many ailments. The recipes soda solutions, which helps to overcome sickness, very simple and accessible to all.

Silicone is silicone material, soft and plastic, so it is used for making various forms for statues and figures. Most just cook at home silicone rubber.

There is no more accurate way to determine sides of the world, than navigating with the compass. Scientists believe that this amazing device was invented in China over 4000 years ago. But imagine the situation, no compass, and the direction to calculate vital. What to do? Most importantly no retreat, no surrender!

To implement the translation from poundsto Newtons s as such is impossible, since is the unit of measure fundamentally different physical quantities. But it is possible to calculate the force of gravity of the body, knowing the body mass expressed in kilograms using the acceleration of gravity.

In science and everyday life commonly used units of measurement of physical quantities like kilowatts, kilowatt-hours and hours. Each of these units corresponds to a specific physical parameter. Kilowatts measure power, in kilowatt-hours – the energy (work) and hours of time. In practice often we have to translate some values in others, for example, the power into energy. At the same time, it is also necessary to translate and the appropriate units – kWh per kW h. This translation is quite possible, if the time is known in advance or it can be calculated.

When solving physical and chemical problems is sometimes required to translate milligrams to milliliters. Although this is a completely different unit of measure this conversion is usually straightforward. You just know the density of the substance, or its name. In most cases, the translation of milligrams per milliliters of produced water or very weak solutions. In this case, to translate milligrams to milliliters much easier.

Sometimes a situation arises when you need to measure the resistance of the power cord (possible breakage) or to test the fuse, bulb, faulty heating element, and the like. With the help of multimeter these tasks are easy.

At first glance, the phrase in the headline, it sounds absurd, as in tons, it is customary to measure body weight and in cubic meters – the volume. Nevertheless, a question or feedback to him occurs often enough. For example, manufacturers sell their products by the ton, and to transport in addition to the mass required dimensions of the product.

Copper products can be very beautiful, and the temptation to do something copper with his own hands. For this purpose the metal must be melted. In the foundry business for the most part there are three main varieties of this metal: pure red copper and its alloys: bronze and brass.

Electrolytic capacitor is an unusual electronic component that combines the properties of a passive element and a semiconductor device. Unlike a conventional capacitor, it is a polar element.

The coordinates of the object can be recorded in several ways: in degrees, minutes, and seconds (the old method), in degrees and minutes with decimal fraction, and in degrees with a decimal fraction (the modern version). Now used all three ways, creating a need for translation of geographic coordinates from one system to another.

Fahrenheit is an obsolete, but still used unit of temperature. To the 70-ies of the last century it was the main in many English-speaking countries. Currently used only in the United States, Belize and Jamaica, for domestic purposes. Are marked the degrees Fahrenheit symbol "°F". Point melting ice on the Fahrenheit scale corresponds to +32 °F and the boiling point of water: 212 degrees F. Zero degrees Fahrenheit is determined by the temperature of the freezing mixture of ice, water and ammonia, and a hundred degrees Fahrenheit corresponds to human body temperature. To convert degrees Celsius to degrees Fahrenheit use the formula is simple and many online services.

At the fork, sockets, fuses, machines, counters, etc. set the maximum current, expressed in amperesAh. But the point appliances power consumption is expressed in watts or kilowatts. How do you know what the maximum load capacity can be enabled by using one or another accessory?

Currently, depending on the situation, there are different ways of measuring length. One of these units is the "linear meter". The name is intimidating, but in fact, this unit is nothing special.

Acetic essence - is acetic acid, an aqueous solution which has a concentration of from 70% to 80%. Is a clear, colorless liquid with a characteristic sharp, hot smell. These concentrations represents a corrosive and highly toxic substance. Not accidentally, in many countries (including, earlier in the USSR) acetic essence allowed to sell in containers of irregular shape, to exclude the possibility of its accidental use in place of other liquids. How to obtain the vinegar essence?

In some countries, the area of apartments and homes consider hundreds of square meters, and the area of plots in hectares. In Russia, occupying 1/6 of the land in acres is generally measured by square plots, and the usual unit of housing area is the square meter. Moreover, to measure every square meter sometimes you need accuracy to the square inch.

Leather is a great material for making a variety of useful items. Watch straps, bookmarks for books, cases for keys, or the covers of the notebooks, made of leather, can be a wonderful gift. This souvenir can be supplemented with beautiful embossing.

All types of organic fuel - oil and its derivatives, gas, coal, firewood, peat is not equivalent to incineration. They have different energy reserves. But for calculations it is necessary to know the quantity stored in them energy. Therefore, for convenience of calculations in power engineering uses the concept of conditional fuel. Conventional fuel is called the fuel, the heat of combustion is equal to 7.000 kcal. 1 kg.

At first glance, the process of translating ounces to grams may be needed only when performing tasks in some disciplines, e.g. physics, mathematics or chemistry. However, such actions may be useful even to the housewife in the kitchen. It is often suggested in recipes of dishes of the same ingredients given in milliliters, grams. So, the skills of this kind can actually be helpful.
