Supported Units

This converter supports the following units of weight/mass:

  • Tonne (t)
  • Kilogram (kg)
  • Gram (g)
  • Milligram (mg)
  • Microgram (µg)
  • Imperial Ton (long ton)
  • US Ton (short ton)
  • Stone (st)
  • Pound (lb)
  • Ounce (oz)

🔢 Conversion Process

All conversions are performed by first converting the input value to a base unit (kilograms, kg) and then converting from kilograms to the target unit. The "Visual Calculation" section illustrates this:

  1. Input Value [Original Unit] → Value in Kilograms (kg)
  2. Value in Kilograms (kg) → Output Value [Target Unit]

Key conversion factors (approximate): 1 kg ≈ 2.20462 lb; 1 lb = 16 oz; 1 stone = 14 lb; 1 tonne = 1000 kg.
