Convert length, weight, volume, and temperature units
Frequently Asked Questions
Length (miles, kilometers, meters, feet, inches, centimeters), weight (pounds, kilograms, ounces, grams), volume (gallons, liters, cups, milliliters), and temperature (Fahrenheit, Celsius, Kelvin).
Length, weight, and volume use simple multiplication (a fixed ratio), but temperature scales have different zero points, so conversion needs an offset too: °F = °C × 9/5 + 32, and °C = (°F − 32) × 5/9.
The US uses customary units (inherited from British imperial units) for everyday measurement, while most of the world uses the metric system. This converter bridges both so you can work with either.
