How to Convert BCM to Mcft
- 1 BCM = 35314.66672 Mcft
- 1 Mcft = 0.00002831684659 BCM
- Example: convert 15 BCM to Mcft: 15 BCM = 15 × 35314.66672 Mcft = 529720.0008 Mcft
Formula
Mcft = BCM × 35314.66672149
Derivation from SI units:
- 1 BCM = 10⁹ m³ = 1000 MCM = 1 km³.
- 1 Mcft = 10⁶ ft³ = 0.028316846592 MCM.
- 1 BCM = 1000 MCM ÷ 0.028316846592 MCM per Mcft = 35314.66672149 Mcft
Both units are defined exactly, so the factor is exact. BCM definition: billion cubic metres; Mcft definition: million cubic feet.
Worked examples
- A reading of 2 BCM converts to 70629.33344 Mcft.
2 BCM × 35314.66672 = 70629.33344 Mcft - A value of 30 BCM is 1059440.002 Mcft.
30 BCM × 35314.66672 = 1059440.002 Mcft
