Why do barometers have different centre readings? I thought 1000 mbar

some newer ones with 1010 as the centre.

On mine it's 29.5 inches

Snap.

Are you one of those Merkins?

y barometer has the name of an old established Edinburgh company on the
dial.

And ours has the name of a Brighton company on it - but not on the dial,
as it hasn't got one, being a traditional mercury barometer.
