What this converter does
This converter turns gas flow in cubic feet per hour into cubic metres per hour and back. It also covers SCFM and litres per minute — every pair uses an exact fixed factor. Type a flow, pick your units, and read the result instantly.
One cubic foot per hour equals about 0.0283 m³/h. US gas appliances are rated in CFH, so converting to metric matches European meters and pipe tables.
The units it covers
Every gas-flow unit is a volume per unit time, so each converts through cubic metres per hour with a fixed ratio.
View all units & their values
| Unit | Symbol | Value | Mainly used |
|---|---|---|---|
| Cubic metre per hour | m³/h | 1 | The base — metric gas metering |
| Cubic foot per hour | CFH | 0.0283 | US gas appliances & meters |
| Standard cubic foot per minute | SCFM | 1.699 | US industrial gas flow |
| Litre per minute | L/min | 0.06 | Small gas & lab flows |
| Cubic metre per second | m³/s | 3600 | Large process flows |
The formula
Each unit has a fixed value in cubic metres per hour, so converting between any two means going through m³/h once:
result = value × factor_from ÷ factor_toWhere:
- value = the flow you typed, in the “from” unit
- factor_from = the “from” unit’s value in m³/h
- factor_to = the “to” unit’s value in m³/h
Worked example
Convert 1000 CFH to cubic metres per hour.
1 CFH = 0.0283168 m³/h1000 × 0.0283168 = 28.32 m³/hSo 1000 CFH is about 28.3 m³/h — a mid-size commercial gas load.
The units in this example
The US unit for gas appliance and meter ratings — one cubic foot of gas flowing per hour.
- 1 CFH = 0.0283 m³/h
- 1000 CFH = 28.3 m³/h
- 1 CFH ≈ 0.472 L/min
- 60 CFH = 1 CFM
The metric unit for gas metering and pipe sizing, used across Europe and most of the world.
- 1 m³/h = 35.31 CFH
- 1 m³/h = 16.67 L/min
- 1 m³/h ≈ 0.589 SCFM
- 1 m³/h = 1000 L/h
