Math & Converters
Unit Converter
Convert length, weight, and temperature units instantly across meters, kilometers, feet, inches, miles, kilograms, grams, pounds, ounces, Celsius, Fahrenheit, and Kelvin.
Formula Explanation
Length/weight: value x from factor / to factor; Temperature: convert to Celsius, then to target unitLinear units use base-unit factors, while temperature requires offset-aware formulas because Fahrenheit and Kelvin do not share the same zero point.
Step-by-Step Example
- 1Choose length, weight, or temperature as the conversion category.
- 2Validate that selected units belong to the chosen category; otherwise defaults are used.
- 3For length and weight, convert the input to a base unit first.
- 4For temperature, convert to Celsius first, then convert Celsius to the target unit.

FAQ
If a unit does not belong to the selected category, the calculator falls back to sensible defaults to prevent invalid conversions.
Multiply Celsius by 9/5 and add 32.
One pound equals 0.45359237 kilograms, so pounds are multiplied by that factor.
No. Temperature conversions require offsets, while length and weight use simple proportional factors.
