1 cm = 10 mm18 cm = 180 mm
18 cm equals 180 mm. 10 millimeters = 1 centimeter
18 cm = 180 mm.
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.
First convert to the same unit (1 cm = 10 mm). Then do the subtraction.
Answer18 inch = 457.2 millimeter Direct Conversion Formula18 in*25.4 mm1 in=457.2 mm18 inches is 457.2 mm
By unit of length and distance and conversion ,we can say that 1 cm=10 mm 1780 mm=178 cm
1 cm = 10 mm18 cm = 180 mm
180 mm
180 mm 1 cm = 10 mm 1 mm = 0.1 cm
1 cm = 10 mm 180 cm = 1800 mm
18 cm = 180 mm
Convert to the same units, then the comparison and calculation can be made. 1 cm = 10 mm → 142 cm = 142 × 10 mm = 1420 mm 1420 > 1240 → the person 142 cm is taller. 1420 - 1240 = 180 mm → they are 180 mm = 180 ÷ 10 cm = 18 cm taller.
1 cm = 10 mm 20 cm x 10 = 200 mm 200 - 20 = 180 mm = 18 cm
18 cm equals 180 mm. 10 millimeters = 1 centimeter
18 cm = 180 mm.
There are 18 cm in 180 mm
