Length Conversion Calculator

Millimeters, centimeters, meters, kilometers, inches, feet, yards, and miles.

The field you enter is highlighted as the source. Editing another result makes that field the new source.

Weight Conversion Calculator

Metric tons, kilograms, grams, pounds, ounces, and US short tons.

Pounds and ounces use the avoirdupois system. “US ton” means a 2,000-pound short ton.

Pressure Conversion Calculator

Bar, kilogram-force per square centimeter, and pounds per square inch.

This converts pressure units only; it does not change gauge pressure to absolute pressure.

Volume Conversion Calculator

Milliliters and liters with US customary fluid ounces, cups, pints, quarts, and gallons.

US customary fluid units are used; UK imperial fluid units have different values.

Temperature Conversion Calculator

Celsius and Fahrenheit conversions with the full offset-and-scale formula.

Temperature conversion uses both multiplication and an offset; it is not a simple unit factor.

Unit conventions

Length uses the international inch definition. Weight uses avoirdupois pounds and ounces, with “US ton” meaning the 2,000-pound short ton. Volume uses US customary fluid measurements. kgf/cm² is kilogram-force per square centimeter using standard gravity.
