How to Convert Mcft to MCM
- 1 Mcft = 0.02831684659 MCM
- 1 MCM = 35.31466672 Mcft
- Example: convert 15 Mcft to MCM: 15 Mcft = 15 × 0.02831684659 MCM = 0.4247526989 MCM
Formula
MCM = Mcft × 0.028316846592
or MCM = Mcft ÷ 35.31466672149
Derivation from SI units:
- 1 Mcft = 10⁶ ft³ = 0.028316846592 MCM.
- 1 MCM = 10⁶ m³ = 1 hm³ (cubic hectometre).
Both units are defined exactly, so the factor is exact. Mcft definition: million cubic feet; MCM definition: million cubic metres.
