By unit of length and distance and conversion ,we can say that
1 cm=10 mm
90 mm =9 cm
It is: 90mm = 9cm
90mm there are 10mm in a centimeter
90 mm is equal to 9 centimeters because 1 centimeter is equal to 10 millimeters.
90mm / 2 = 45 mm
83
Uhhh ......... Kinda depends on your exact definition of "90mm" there. Is it a 1) shell (aka: a round of ammo)? 2) complete/partial field gun (howitzer)? The question needs some clarification ......
10mm = 1cm so 90mm = 9cm
A megameter is much larger than a centimeter.
1 decimeter = 10 centimeter
1 centimeter=10,000 micrometers
== 1 centimeter== 10mm == 1 centimeter= 10mm 8 mm= .8 centimeter === ===
ten millimeters are in a centimeter.
