Convert units with dimensional analysis. Enter a value, pick a starting and target unit, and see every factor-label rung of the ladder with the units cancelling step by step.

The Dimensional Analysis Ladder converts a quantity between units using the factor-label method. Enter a value, choose a starting unit and a target unit, and every rung of the ladder is written out with the conversion factor as a fraction so you can watch the units cancel.
It supports length, mass, time, and volume units, converting through each category's base unit — meter, gram, second, and liter. Units from different categories, and temperature scales that need an additive offset, are rejected with an explanation instead of a wrong answer.
Dimensional analysis, also called the factor-label method, converts a quantity from one unit to another by multiplying by conversion factors that each equal 1. Because every factor equals 1, only the unit label changes — the quantity stays the same size.
Each conversion factor is written as a fraction with the unit you want to remove in the denominator. That label cancels against the quantity you started with, leaving the new unit behind.
Meters measure length and grams measure mass, so no conversion factor connects them. Both units must belong to the same dimension category: length, mass, time, or volume.
No. Celsius, Fahrenheit, and Kelvin conversions need an additive offset rather than a pure multiplicative factor, so they fall outside the factor-label ladder and are treated as unsupported units.
