Convert between length, weight and volume units across metric and imperial systems.
Every unit is converted through a common base unit (meters for length, grams for weight, liters for volume), so any combination — millimeters to miles, or grams to pounds — stays accurate to standard SI definitions.
Both metric (mm, cm, m, km, g, kg, ml, l) and imperial/US customary (inch, foot, mile, ounce, pound, gallon) units are included.
