Back

Dimensional Analysis


A problem-solving technique that uses the cancellation of units to obtain the correct solution, also known as the Unit Factor Method.

Example: This diagram shows how to use dimensional analysis to convert units, like changing 24 inches to feet by multiplying with a conversion factor and canceling units.

SI Prefix Noun

[es-ahy pree-fiks]

Back

SI Prefix


A word or symbol placed before a unit that multiplies that unit by a specific power of 10, like kilo- or milli-.

Example: This chart shows common SI prefixes (like kilo-, centi-, milli-), their corresponding power-of-10 values, and a mnemonic to remember their order for unit conversions.

Conversion Factor Noun

[kuhn-vur-zhuhn fak-ter]

Back

Conversion Factor


A ratio or fraction that is numerically equivalent to one and is used to convert a quantity from one unit to another.

Example: To convert units, multiply by a conversion factor, a fraction equal to one (e.g., 12 in / 1 ft), to cancel the old unit and get the new one.
