How to Convert Mcft to Gigalitre
- 1 Mcft = 0.02831684659 GL
- 1 GL = 35.31466672 Mcft
- Example: convert 15 Mcft to GL: 15 Mcft = 15 × 0.02831684659 GL = 0.4247526989 GL
Formula
GL = Mcft × 0.028316846592
or GL = Mcft ÷ 35.31466672149
Derivation from SI units:
- 1 Mcft = 10⁶ ft³ = 0.028316846592 MCM.
- 1 GL = 10⁹ L = 10⁶ m³ = 1 MCM.
- 1 Mcft = 0.028316846592 MCM ÷ 1 MCM per GL = 0.028316846592 GL
Both units are defined exactly, so the factor is exact. Mcft definition: million cubic feet; Gigalitre definition: gigalitre.
Worked examples
- A reading of 100 Mcft converts to 2.831684659 GL.
100 Mcft × 0.02831684659 = 2.831684659 GL - A value of 2000 Mcft is 56.63369318 GL.
2000 Mcft × 0.02831684659 = 56.63369318 GL
