Question

How many mm are in \[50\] cm?

Answer 1

Hint: In the given question, we have been given to convert one unit of measurement to another. We have to convert some given number of centimeters to millimeters. Here, we convert centimeters to millimeters by first writing the relation between a centimeters and millimeters and then multiplying by the given number of centimeters with it. It is thus important that we know how many millimeters there are in a centimeter.
We are going to use the relation between centimeters and millimeters, which is,
\[1cm = 10mm\]

Complete step by step answer:
We have to convert \[50\]cm to mm.
To do that, we multiply the conversion of one centimeter to millimeter by \[10\],
\[1cm = 10mm\]
So, \[50cm = 50 \times 10 = 500mm\]

Note: In the given question, we had to convert centimeters to millimeters. We solve these questions by writing the relation between the two units and then following that relation to solve for the value. A lot of students make mistakes when they write the relation between the two quantities; they do not remember the power of ten values to be multiplied with the number. So, it is important that we remember the relation between all the metric units.
