You can now get the hugely popular Gas Rate Calculator & Guide on your iPhone or iPad. This is the free Lite version of the app to which supports metric and imperial meters with natural gas only.
Input the initial meter reading, use the built in 2 minute timer and then input the final reading. Press the calculate button and the results will then be displayed.
The app comes with a built in stopwatch and could not be easier to use: start the stopwatch and after a complete rotation of the test dial press stop and the results will be displayed instantly!
Gas rates are given in cubic metres per hour, litres per second and cubic feet per hour. Gross and net heat inputs are given in megajoules per hour, kilowatts and BTUs per hour.
We've made some small tweaks for iOS 12.
