How to Convert TMC to Gigalitre
- 1 TMC = 28.31684659 GL
- 1 GL = 0.03531466672 TMC
- Example: convert 15 TMC to GL: 15 TMC = 15 × 28.31684659 GL = 424.7526989 GL
Formula
GL = TMC × 28.316846592
Derivation from SI units:
- 1 TMC = 10⁹ ft³ = 28.316846592 MCM.
- 1 GL = 10⁹ L = 10⁶ m³ = 1 MCM.
- 1 TMC = 28.316846592 MCM ÷ 1 MCM per GL = 28.316846592 GL
Both units are defined exactly, so the factor is exact. TMC definition: TMC; Gigalitre definition: gigalitre.
Worked examples
- A reading of 10 TMC converts to 283.1684659 GL.
10 TMC × 28.31684659 = 283.1684659 GL - A value of 100 TMC is 2831.684659 GL.
100 TMC × 28.31684659 = 2831.684659 GL
