To calculate how many kilometers per liter you are getting in your car, divide the number of miles driven by the number of liters used. If you've travelled 140 kilometers on 11 liters of gasoline, you divide 140 by 11 to reach 12.73 kilometers per liter.
To find these two numbers, make note of the number of kilometers on your car's odometer the next time you stop for gasoline. The next time you fill up, subtract the first number from the current number on the odometer. This will be the number of kilometers travelled which you will then divide by the number of liters it takes to fill your car's tank.
Learn MoreTo convert from molecules to grams, it is necessary to first convert the number of molecules of a substance by dividing by Avogadro's number to find the number of moles, and then multiply the number of moles by the molar mass of this substance. Avogadro's number is given as 6.022 x 10^23.
Full Answer >If you are calculating area or performing other calculations, it is often useful to convert metric units of measure to standard units of measure. With a simple equation, you can quickly convert centimeters to inches.
Full Answer >One liter is the equivalent of approximately 0.2642 gallons. As both terms are measurements of volume, one can convert between the two by utilizing the fact that there are about 3.785 liters per gallon.
Full Answer >To convert kN/m2 to kg/m2, multiply by approximately 102 seconds squared per meter, which is 1000/9.8 seconds squared per meter. The conversion of units of force, such as kilonewtons, to units of mass, such as kilograms, assumes that the mass is subject to an acceleration, most often the acceleration of gravity, which is typically around 9.8 meters per second near the earth's surface. However, the precise figure can vary slightly with location.
