90mm x 45mm is what’s available near me for framing timber. And yes it’s more accurate.
Millimetres in general are used heavily in construction, everything is stated in them, even into the thousands where people normally would have switched to metres.

Similar thing in the US but with inches vs feet. In framing, no one would ever call for a "3 foot 2 and a half inch block," it's just "38 and a half"
