How to Convert Gigalitre to Mcft
- 1 GL = 35.31466672 Mcft
- 1 Mcft = 0.02831684659 GL
- Example: convert 15 GL to Mcft: 15 GL = 15 × 35.31466672 Mcft = 529.7200008 Mcft
Formula
Mcft = GL × 35.31466672149
Derivation from SI units:
- 1 GL = 10⁹ L = 10⁶ m³ = 1 MCM.
- 1 Mcft = 10⁶ ft³ = 0.028316846592 MCM.
- 1 GL = 1 MCM ÷ 0.028316846592 MCM per Mcft = 35.31466672149 Mcft
Both units are defined exactly, so the factor is exact. Gigalitre definition: gigalitre; Mcft definition: million cubic feet.
Worked examples
- A reading of 5 GL converts to 176.5733336 Mcft.
5 GL × 35.31466672 = 176.5733336 Mcft - A value of 100 GL is 3531.466672 Mcft.
100 GL × 35.31466672 = 3531.466672 Mcft
