How many micrometers are in a millimeter?

Answer 1

1000 micrometers per millimeter
1000 'Micro' indicates 'millionth' and 'milli' indicates 'thousandth'. There are 1000 millionths in a thousandth, and hence 1000 micrometers (or microns) in a millimeter.

There are one million micrometers in one metre. There are 1000 millimeters in one meter.
There are 1000 micrometers to a millimeter (mm).

A micrometer (μm) is one-millionth, 1/1000000 of a meter (1 x 10-6 m) and

a millimeter (mm) is one-thousandth, 1/1000 of a meter (1 x 10-3 m).

So a millimeter is 1000 times the length of a micrometer.
1mm in micrometers is 1000um.

i couldn't do the um bit right :(
it is the same sise as a cow.
1mm is 10-4 time bigger the 1 micrometer.

Answer 2

1 micrometre = 1/1000 millimetres or 0.001mm
