How to Convert Liter to Milliliter
- 1 L = 1000 mL
- 1 mL = 0.001 L
- Example: convert 15 L to mL: 15 L = 15 × 1000 mL = 15000 mL
Formula
mL = L × 1000
Derivation from SI units:
- 1 L = 1 dm³ = (0.1 m)³ = 10⁻³ m³
- 1 mL = 10⁻³ L = 1 cm³ = 10⁻⁶ m³
- 1 L = 0.001 m³ ÷ 0.000001 m³ per mL = 1000 mL
Both units are defined exactly, so the factor is exact. Liter definition: liter; Milliliter definition: milliliter.
Worked examples
- A 1.5 L bottle holds 1500 mL.
1.5 L × 1000 = 1500 mL - 0.25 L is 250 mL.
0.25 L × 1000 = 250 mL
