Cubic meters at IUPAC STP to normal cubic meters
Type a value in m³ (STP) to get it in Nm³ instantly.
98.69Nm³
That's 9.9× as much as a 50 L cylinder at 200 bar, while an LNG tanker’s cargo is 1,021,993× more. As methane that is 70.63 kg, about 1,089 kWh of heat.
What it means
How much gas is that?
Ideal gas law. Real natural gas deviates by under half a percent at these conditions. Some contracts define Sm³ at 20 °C; check yours.
The math
How to convert m³ (STP) to Nm³
To convert cubic meters at IUPAC STP to normal cubic meters, multiply by 0.986923.
Example: 100 m³ (STP) × 0.986923 = 98.6923 Nm³.
In the other direction, 1 Nm³ = 1.01325 m³ (STP).
