if you're working to two decimal places on the Celsius scale then at sea level water doesn't boil at 100.00 °C but rather at either 99.98(4) or °C 99.97(4) °C depending on method of calibration.Mick F wrote: ↑27 Oct 2022, 10:29am Listening to Money Box on R4 the other day, and a lady (ex science teacher) worked out how much she can save on her lecky bill by turning off her automatic electric kettle manually as soon as it reached 100degC. It was surprising how much lecky was used for those ten seconds added up to over a year.
Now, I'm no scientist, and I see her point, but she as an ex science teacher should know that water only boils at 100degC as sea-level.
We live at about 250ft, and people up the hill at 750ft.
If we lived in Princetown up on Dartmoor we would be at 1,400ft.
Found the calculator site.
Interesting eh?

Water boils in Princetown at 98.62degC ................ and that doesn't include barometric pressure variations!
