From cooking measurements to construction materials, converting between units shouldn’t require a calculator. Our Unit Converter handles length, weight, volume, area, speed, and energy conversions seamlessly.
Unit Converter
Convert between different units of measurement — length, mass, volume, area, speed, and more.
How the Unit Converter Works
All conversions are based on a standard reference unit within each category:
- Length: 1 meter (m) is the base — 1 km = 1000m, 1 mile = 1609.34m
- Weight: 1 kilogram (kg) is the base — 1 lb = 0.4536 kg
- Volume: 1 liter (L) is the base — 1 gallon = 3.785 L
- Area: 1 square meter (m²) is the base — 1 acre = 4046.86 m²
- Speed: 1 m/s is the base — 1 km/h = 0.2778 m/s
- Energy: 1 joule (J) is the base — 1 kWh = 3,600,000 J
