How to Convert Mcft to BCM
- 1 Mcft = 0.00002831684659 BCM
- 1 BCM = 35314.66672 Mcft
- Example: convert 15 Mcft to BCM: 15 Mcft = 15 × 0.00002831684659 BCM = 0.0004247526989 BCM
Formula
BCM = Mcft × 0.000028316846592
or BCM = Mcft ÷ 35314.66672149
Derivation from SI units:
- 1 Mcft = 10⁶ ft³ = 0.028316846592 MCM.
- 1 BCM = 10⁹ m³ = 1000 MCM = 1 km³.
- 1 Mcft = 0.028316846592 MCM ÷ 1000 MCM per BCM = 0.000028316846592 BCM
Both units are defined exactly, so the factor is exact. Mcft definition: million cubic feet; BCM definition: billion cubic metres.
Worked examples
- A reading of 100 Mcft converts to 0.002831684659 BCM.
100 Mcft × 0.00002831684659 = 0.002831684659 BCM - A value of 2000 Mcft is 0.05663369318 BCM.
2000 Mcft × 0.00002831684659 = 0.05663369318 BCM
