1 L = 1,000 mL

The metric volume ladder

  • 1 L = 1000 mL · 1 m³ = 1000 L.
  • 1 mL = 1 cm³ — handy bridge between length and volume.
  • A teaspoon ≈ 5 mL, a fizzy-drink can = 330 mL, a big water bottle = 1.5 L.
Your turn

A fish tank is 50 cm × 30 cm × 40 cm. How many litres does it hold?

1 litre of pure water has a mass of exactly 1 kg (at 4 °C) — that's no accident, it's how the litre and kilogram were originally tied together.

Conversions

  • 1 L = 1000 mL
