Advice 1: How to calculate the volume in liters

To calculate the volume of a body or substance to litersyou need the quantity expressed in other units. If body volume is unknown beforehand, it can be calculated using mass and density. For measuring mass and density, there are special methods and tools.
How to calculate the volume in liters
You will need
  • calculator, scales, tables of the density of a substance
Instruction
1
If the volume specified in cubic decimeters (dm3) the volume in litres expressed to the same number. So just change the unit of measure to dm3 litre (l).
Vл=Vдм3Для translation in liters volume, given in cubic meters (m3), multiply the specified numeric value to 1000.
Vл=Vм3*1000Чтобы translate in liters volume specified in cubic centimeters (cm3) or Millilitres (ml), divide the given numeric value to 1000.
Vл=Vcм3/1000=Vмл/1000.To calculate the volume in liters, if it is set to Dekaliters (l) or pails, multiply the number of deciliters 10:
Vл=Vдл*10

If the amount specified in non-metric units (national or household), use the following instructions:If the unit of measure of known volume is the us gallon, to calculate the volume in liters, multiply by 3,7854. Similarly dealing with other volume units:U.S. quart – multiply by 0,9464;
a us gallon is 3,7854;
a us dry barrel – 115,6270;
American bushel – 35,2391;
us liquid barrel 119,2400;
the oil barrel is 158,9873;
the Imperial gallon – 4,5461;
Imperial quart – 1,1365;
Imperial pint 0,5683;
Imperial ounce 0,0284;
the American pint 0,4732;
American ounce 0,0296;
Imperial bushel – 36,3687;
teaspoon – 0,005;
tablespoon - 0.0148;
circle – of 1.23 (shareware);
glass – 0,2;
cubic inch is 0,0164;
cubic foot – 28,3168.

If the volume of the solid or liquid is unknown, calculate it using the following formula:
V=m*p, where:
V – the desired volume,
m is the mass of the body fluids or substances
p is its density.If the body weight is unknown, then determine its weighting. The density of matter find it in the table of density.
The resulting value of the volume will be in litersif the mass is specified in grams (g), and density is in grams per liter (g/l). In other cases, recalculate the volume in liters, using the above instructions.
Useful advice
Note that the density of water is equal to 1000 g/l or 1 kg/l or 0.001 t/l. Therefore, to calculate in liters of a known mass of water, simply:
mass in grams, divide by 1000;
mass in tons, multiply by 1000;
the mass of water in kilograms take is equal to the volume in litres.

Advice 2: How to convert liters to milliliters

When working with small volumes are often used as a unit of volume like milliliter (ml). A milliliter is called a thousandth of a liter. That is, in one liter contains one thousand milliliters. To convert liters to milliliters you don't even need the calculator – fairly simple maths.
How to convert liters to milliliters
You will need
  • pencil,
  • paper.
Instruction
1
To convert liters to milliliters, simply multiply the number of liters per thousand. That is, apply the following simple formula:

KML = KL x 1000 where

KML is the number of milliliters,
KL – the number of liters.

For example, one teaspoon contains about 0,005 liters of fluid. Consequently, the volume of a teaspoon, expressed in milliliters, is: a 0.005 x 1000 = 5 (ml).
2
If the number of liters is an integer, to translate liters to milliliters just attribute to the number of gallons right three zero.

For example, in one bucket fits about 10 liters of water. Thus, the volume of this water in milliliters would be: 10 x 1000 = 10 000 (ml).
3
If the number of gallons specified as a decimal fraction, shift the decimal point three digits to the right.

For example, a kilogram of gasoline occupies a volume approximately 1,316 litres. Therefore, in milliliters kilogram of gasoline will have a volume of 1316 (ml).
4
If the decimal point is less than three digits, add the missing digits with zeros.
For example, in one glass fits 0.2 liters of liquid. Milliliters it will be – 200 (ml) (formally obtained 0200 ml, but non-significant zero to the left can be discarded).
5
If all the source data of the task is set in litres, and the result is required to be provided to milliliters, all intermediate calculations spend in liters and in milliliters move only after finishing all calculations.

For example, if for the preparation of paint of the desired shade was mixed 1,325 litres of black paint, 0,237 liters red, green 0,587 liters and 0.54 liter blue, then count the total amount of dye in milliliters fold the quantities specified in liters, and multiply the result by 1000.
1,325 + 0,237 + 0,587 + 0,54 = 2,689
2,689 x 1000 = 2689 (ml).
Note
Translation of liters in a milliliter is often used in the calculations related to preparation of drugs and other active solutions. In such calculations, be very careful – error only one decimal place, the result will change ten times.
