Convert between cubic metres and litres

Basic Conversion Rule

  • 1 cubic metre = 1,000 litres
    📏💧
  • 1 m³ = 1000 L
  • 1 L = 0.001 m³

💡 Why 1 m³ = 1000 L?

  • A cubic metre (m³) is a cube that measures:
    📦 1 m × 1 m × 1 m
  • In millilitres:
    1 m = 100 cm → so
    1 m³ = 100 cm × 100 cm × 100 cm
    = 1,000,000 cm³ = 1,000,000 mL
  • Since 1,000 mL = 1 L1,000,000 mL ÷ 1000 = 1,000 L

🔄 Conversion Formulas

Convert ToUse FormulaExample
m³ → LMultiply by 10002 m³ = 2 × 1000 = 2000 L
L → m³Divide by 10003500 L ÷ 1000 = 3.5 m³

🧠 Quick Mental Tips

  • To convert m³ to L 👉 add three zeros
    e.g., 0.6 m³ → 600 L
  • To convert L to m³ 👉 remove three zeros
    e.g., 7500 L → 7.5 m³

🧊 Real-Life Examples

🌊 Water Tank Capacity: A tank of 4 m³ holds 4000 L of water.
🏊‍♂️ Swimming Pool: A pool with 12 m³ of water has 12,000 L.
🚗 Car Radiator: 5 L of coolant = 0.005 m³.


🧪 Remember Units

  • Use when dealing with large volumes (tanks, pools, reservoirs).
  • Use L for smaller quantities (bottles, buckets, containers).

🔍 Small Unit Relationship

  • 1 L = 1000 mL
  • 1 m³ = 1000 L
    → So, 1 m³ = 1,000,000 mL

🌟 Summary:
🧊 1 m³ = 1000 L and 1 L = 0.001 m³.
Use ×1000 to convert m³ to L, and ÷1000 to convert L to m³.

Learn with an example

1 cubic centimetre = 1 millilitre

1 litre = 1,000 millilitres = 1,000 cubic centimetres

1 cubic metre = 1 kilolitre = 1,000 litres
