Oh, another undefined 'we'!

It depends upon the circumstances. Millimetres of water is a much more convenient scale for, say, air handling, where differential pressures are quite low. Millimetres of mercury is more convenient for, say, measuring high vacuum in pharmaceutical primary manufacture.

So the short answer is that it depends upon what 'we' are doing, and 'we' haven't stated what it is.

Hello PWSlack

Looks like it is time to pour that kettle, for a cup of Earl Grey tea, right about now.

Kind Regards....

"Oh, another undefined 'we'!"

Perhaps our guest has a toad in his pocket?
