About Unit Conversion
All conversions use exact or standard conversion factors. Temperature conversions use the official formulas: °F = (°C × 9/5) + 32, K = °C + 273.15. Volume uses US customary units for gallons, quarts, pints, cups, and fluid ounces. Weight uses metric tons (1000 kg) and imperial tons (2240 lbs).
