About Gas Flow Rate Calculator
The gas rate calculator that does the test with you.
Time the dial with the built-in stopwatch, or run the 2-minute timer for a metric meter, and get gross and net heat input in every unit a UK gas engineer needs — kW, BTU/hr, ft³/hr, m³/hr and l/hr. Then check it against the appliance's data badge and see instantly whether it's within tolerance.
TIME THE DIAL (U6 METERS)
No separate stopwatch. Tap when the test dial passes its mark, tap again on the next revolution, and the seconds drop straight into the calculation. Supports 1/4, 1, 2 and 5 ft³/rev dials.
2-MINUTE TIMER (E6 METERS)
Record the meter reading and start the timer. Walk away if you need to — you'll get a notification when it's time to take the second reading, even with your phone in your pocket.
DATA BADGE CHECK
Enter the appliance's rated heat input in kW or BTU/hr, gross or net, and the app tells you whether it's burning within the ±5% tolerance — and by exactly how much it's out. The question you actually came to answer.
RESULTS IN EVERY UNIT
Every calculation gives you gross and net values for kW, BTU/hr, cubic feet per hour, cubic metres per hour and litres per hour.
THREE GAS TYPES
- Natural Gas (CV 38.76 MJ/m³, gross/net ratio 1.11)
- Propane (CV 93.1 MJ/m³, gross/net ratio 1.09)
- Butane (CV 121.8 MJ/m³, gross/net ratio 1.08)
SAVE, NAME AND SHARE
Save calculations to a history and name them by appliance, job or address. Share any result as text for your job records, invoices or warranty paperwork. History is stored on your device and persists between sessions.
NO SIGN-IN. NO ADS. NO DATA COLLECTED.
All calculations run entirely on your device. Nothing is sent to any server.
Built for iPhone and iPad. Requires iOS 26 or later.
