Answer 3

1 inch=2.54 cms

2.54 cm=2.54*10 mm

              =25.4mm

therefore 1 inch=25.4 mm!!!

Answer 4

approximatly 25 mm = one inch (just under)  as 300 mm 3-15/16 " if you just need it as rule of thumb then 900mm is just under 3 ft (9/16") as far as far as I can see, how ever if you want to be precise then go to metric it is easier G.L.

Just over 25 mm to 1 inch

Answer 10

<<Safaria>> We're not in France, Quebec or any other French-speaking country (with the exception of Quebec), so commas are not used to replace dots. In other words, the French always think they're right, but get it wrong.
