Instruction

1

Re-calculate the original pressure value in Pascal (PA) if it is given in megapascal (MPa). As you know, in one MPa 1 000 000 Pascals. For example, you will need to convert in Pascal 3 MPa, it will be: 3 MPa * 1 000 000 = 3 000 000 PA.

2

Translate the Pascal in pounds of force, knowing the characteristics of the unit pressure in relation to the unit of force (Newton). One Pascal equals one Newton per square meter. The derived unit of force in Newtons is equal to 1 kg / (m/S2), where m/S2 is the acceleration of free fall. For calculations used the value, which is equal to 9.81 m/S2. Calculate the number of kilograms force of one Newton acting on one square meter with acceleration equal to 9.81 m/S2 : - 1 / 9,81 = is 0.102 kilograms of force per square meter, which corresponds to a pressure of one Pascal.

3

Multiply the resulting number by the number of Pascals you want to transfer in pounds: 0,102 * 3 000 000 (PA) = get 306 000 (kg/m2). Thus, the pressure value of 3 MPa corresponds to 306 000 pounds of force per square meter. So, to quickly convert Pascals to kilograms, multiply the pressure in Pascals on the coefficient is 0.102. If you need to translate Pascal to kilograms force per square centimeter, the pressure is in Pascals, you need to multiply by a factor 0,0000102. In this example, the pressure of 3 MPa corresponds to 30.6 kilograms force per square centimeter (3 000 000 PA * 0,0000102 = 30,6 kg/cm2).

Note

The magnitude of the gravitational acceleration used to calculate the conversion factor for Pascals to kilograms of force in accordance with Newton's second law (acceleration equals the force of gravity acting on an object of unit mass). The value of the gravitational acceleration in the technical calculations used equal to 9.81 m/S2.

# Advice 2 : How to convert kilograms to milliliters

The process of translating kilograms to

**milliliters**is a translation of the mass in the volume. A similar problem often found in physics. How to get from mass to volume, kilograms, liters and**milliliters**?Instruction

1

Order of mass to volume, you must know the density of the substance. The density indicates how much mass of a substance is placed in a given volume. Body of the same mass but different densities will have different volumes.

2

Translate available data (mass, density) in standard SI units. Mass must be in kg, density in kilograms per cubic meter.

3

To find volume, use the physical formula that shows the relationship between mass, density and volume. Get the amount in the standard SI unit - cubic meterH.

4

A liter is a unit. 1 liter equal to 1 cubic decimeter, or one thousandth of 1 cubic meter.

5

To convert cubic meters to liters, you should multiply by a thousand. But then to convert liters to

**milliliters**, divide by a thousand. Therefore, the obtained value of volume in cubic meters is numerically equal to the desired value of the volume in milliliters.6

Write down the answer.

# Advice 3 : How to convert MPa to atmosphere

The name of the French scientist and writer Blaise Pascal, who lived in the seventeenth century, called the unit of pressure used in the international system SI. It is equal to the pressure of one Newton distributed on an area of one square meter. In addition to her pressure and indicate to other units, including in the atmospheres. This measure is derived from practical measurements and is equal to the pressure of the earth's

**atmosphere**at sea level.You will need

- A calculator or Internet access.

Instruction

1

Start with the clarification that it is because of two variants of atmospheres you need to as a result of converting the initial value in megapascal. Most often refers to the "standard" or "physical" atmosphere equal to the pressure force which can be balanced by 760-millimeter column of mercury 13595,1 density in kg/m? when the acceleration of gravity, equal to 9,80665 m/s?. These are the density of mercury at 0°C and the Earth's gravity at sea level. But there is also "technical" atmosphere, which is taken equal to the pressure force of the load mass 1kg on a plane area of 1 cm?, perpendicular to gravity in 1Kgs.

2

To determine the rate of the transfer values from the

**MPa**in**the atmosphere**. Assume that one standard atmosphere is equal to 101325 Pascal, and one technical atmosphere corresponds to 98066,5 Pascal. The reduction in**MPa**is indicated by the derivative of the value of Pascal - megapascal. All used SI units prefix mega corresponds to a factor of one million (10?), so the above values should be reduced by six orders of magnitude. Move the comma and get the coefficients 0,101325 and 0,0980665.3

Divide the measured value in megapascal, the conversion factor obtained in the previous step. Since this ratio is not a round figure, calculate in the mind not very convenient. To do this, use a calculator, but if you have access to the Internet, use the computers embedded to many search engines. For example, if you want to translate in the physical

**atmosphere**the pressure is 78**MPa**, then go to the home page of Google and in the search query box enter 78/0,101325. The search engine will calculate and display the result: 78 / 0,101325 = 769,800148.# Advice 4 : How to convert kilograms to kilonewtons

In kilograms, but rather in kilograms-force, measured force in the system MCGSS (short for "Meter, Kilogram, Second"). This set of standards of units of measurement is rarely used today as superseded by another international system - SI. To measure the strength of designed other units called Newtons, so you may have to resort to conversion values from kilogram-force to Newtons and derived units of measurement.

Instruction

1

Determine the accuracy with which you need to translate the original value in

**the kN**. Kilogram-force is defined in the system MCGSS as the force with which we must act on a mass of one kilogram to accelerate it, equal to 9,80665 m/S2 - so since the beginning of the last century, it is recommended to consider the acceleration of free fall on our planet. Round this number depending on the desired accuracy of conversion.2

Assume that one kilogram-force corresponds to unrounded 9,80665 Newtons. As the SI prefix "kilo" fixed multiplier, equal to one thousand units, the kN will match the original ratio, separated by exactly this number: 1 kgf = 0,00980665 kN.

3

Multiply defined in kilogram-force value rounded to the desired precision coefficient 0,00980665 to know the equivalent in kilonewtons.

4

Use any online calculator for converting units of power. For example, it may be placed on the page http://convertworld.com/ru/massa/Килоньютон.html. Downloading it, enter in the box under "I want to translate" original value in kilogram-forces. Then in the drop-down list placed next to the input field, select "Kilogram (kg)", and the following same list, specify the desired number of digits after the decimal point. The result of the conversion you will see once it is placed in the second row of the column titled "Metric" and are labeled "KN".

If Internet access is absent, then make the necessary calculations themselves, using, for example, the standard calculator from the Windows operating system. The link to his search for run in the main OS menu, opened by clicking on the "start"button.

# Advice 5 : How to convert ton-force into kilograms

**Ton-force**refers to non-si units of force and weight. Often to measure the strength and weight use other units, such as kilogram-force. In order to translate ton-force to

**pounds-force**, you must do the following.

Instruction

1

Put the amount in tonnes-force to pounds-force, multiply the original number by 1 000, as one ton-force the thousands of pounds of force.

2

Take advantage of a proven statement that one kilogram-force is equal to the weight of a body of mass one kilogram with the message that the body acceleration equal to 9,80665 m/S2, to convert ton-forces in SI units (Newton). According to him, one ton-force is equal to 9806,65 Newtons (N). So to put non-systemic force (ton-

*force*) SI units (Newton), must the source the amount of ton-force multiplied by the number 9806,65.3

Use the Converter unit conversion to quickly convert ton-force into kilograms-force, or other interested units.

4

Open the Converter unit conversion. Select the desired section by clicking on it with the pointer of "mouse". In this case, select "Power". In the opened window you must fill in the fields as follows.

5

Enter the number of tons of force, which should be transferred. If you enter a number with tenths to separate the use point. In the next box click on the arrow to open the list, select the unit to convert to, in this example, ton-force.

6

Select "mouse" tick in the list of units next to those that need to translate the original value. Put it in front of the kilograms-force.

7

Click on the "Translate" button. Wait for the result. In the "output are of the form" will indicate the initial number of tonnes-force and translation results - the number of kilograms-force. So using the currency Converter, you can easily translate any quantity in different units.

Note

Between mass and weight have not previously made the distinction. In kilograms was measured not only the weight but also the weight (force of gravity). Kilogram-force as a separate unit of force and weight, was introduced in 1901 at the third General conference on weights and measures. In the International system of units to measure was adopted by the unit Newton.
