How it works
Convert length (meters, kilometers, centimeters, miles, yards, feet, inches), weight (kilograms, grams, tonnes, pounds, ounces), temperature (°C, °F, K), area (m², hectares, acres, ft²), volume (liters, mL, m³, US gallons, fl oz, cups) and speed (km/h, m/s, mph, knots).
Common conversions: 1 inch = 2.54 cm, 1 foot = 30.48 cm, 1 mile = 1.609 km, 1 lb = 0.4536 kg, °F = °C × 9/5 + 32.
