How many millimeters does it take make a meter?

Answer 1

there are a thousand millimeters in a meter

An easier way to do this would be to break it down first.

we know that there are 100 centimeters in a meter.

we also know that there are 10 millimeters in a centimeter.

so 10(millimeters in a centimeter) x(times) 100(centimeters in a meter)

...10x100=1000

one thousand millimeters in a meter

:(. That is NOT the easier way! Learn what the prefixes mean, instead.

The prefix tells you the multiplier, so 'milli' means one-thousandth therefore to turn metres to millimetres multiply them by 1000.

You do NOT break a simple, linear conversion into intermediate steps because that makes additional, extra work and increases the risk of error. You may need to use intermediate steps for more unwieldy calculations involving mixed dimensions, but for straight linear conversions just use the prefix-value directly.
