Key Concepts

Conversion Factor

A conversion factor is a numerical ratio that expresses how many of one unit are equivalent to another unit. It is used to multiply a given measurement in one unit to obtain the measurement in another unit, ensuring the proper cancellation of units.

Dimensional Analysis

Dimensional analysis is a systematic approach to convert between units by multiplying by conversion factors. This technique involves tracking units throughout the calculation to make sure they cancel appropriately, leaving only the desired units in the result.

Unit Conversion

Unit conversion is the process of converting a quantity expressed in one unit into another unit. It involves using known relationships between units, often through conversion factors, to change the measurement without altering its value.
