How unit conversion works
Each unit category uses a base unit (e.g. meters for length, kilograms for mass). Converting A → B multiplies the value by the ratio of their base factors:
- Length — base: meter (m)
- Mass — base: kilogram (kg)
- Temperature — special formulas (°C ↔ °F ↔ K)
- Volume — base: liter (L)
Example: 5 miles → km: 5 × 1.60934 = 8.05 km.
