How many mm 18 cm equal to?
1 cm = 10 mm18 cm = 180 mm
18 cm equals to how many mm?
18 cm equals 180 mm. 10 millimeters = 1 centimeter
How many mms in 18 cms?
18 cm = 180 mm.
WHAT IS 180 mm in cm?
180 mm = 18 cm 10 mm = 1 cm Algebraic Steps / Dimensional Analysis Formula 180 mm*1 cm 10 mm=18 cm +++ You do NOT need Dimensional Analysis, a topic in applied algebra for developing complex formulae, simply to convert between the multiple steps in any one measurement in the Metric System. That's the second answer I have seen so far trying to confuse students by citing advanced mathematics - and then incorrectly. All you need to know for the Metric System is that the units ascend or descend in multiples or divisions of 10, and the names for those X10 steps.
Decrease 20 cm by 20 mm?
First convert to the same unit (1 cm = 10 mm). Then do the subtraction.
