Metric mass

Milligrams, grams, kilograms, tonnes — base 10, easy to scale.

Metric mass scales by tens (and thousands).

Type a value, pick units

1 kg = 1,000 g

The metric mass ladder

  • tonnekggmg — each step is ×1000.
  • 1 t = 1000 kg · 1 kg = 1000 g · 1 g = 1000 mg.
  • A paperclip ≈ 1 g, a litre of water = 1 kg, a small car ≈ 1 tonne.
Your turn

Convert 0.75 kg to grams.

Watch out

Metric mass steps are ×1000, not ×10 — going kg → g jumps three decimal places, not one.

Conversions

  • 1 g = 1000 mg
  • 1 kg = 1000 g
  • 1 t (tonne) = 1000 kg
