Understanding your calculation
Method, example and limitations
How the calculation works
A unit conversion multiplies by the appropriate conversion factor while preserving the measured quantity. Check that both units describe the same physical dimension.
Example to check
One meter equals 100 centimeters. One square meter instead equals 10,000 square centimeters because the factor is squared.
Before using the result
Area, volume, mass, force and energy are different dimensions. Temperature conversion may require an offset as well as multiplication.
