Final answer:
The conversion factor from micrometers (UM) to millimeters (MM) is 1 millimeter equals 1,000 micrometers. To convert, divide the number of micrometers by 1,000.
Step-by-step explanation:
The conversion factor from micrometers (UM) to millimeters (MM) is important to understand when performing unit conversions in mathematics and science. A micrometer is one-millionth of a meter, while a millimeter is one-thousandth of a meter. Therefore, to convert from micrometers to millimeters, you must divide the number of micrometers by 1,000, as there are 1,000 micrometers in a millimeter.
Given that 1 millimeter (mm) = 0.001 meter (m) and 1 micrometer (um) = 10⁻¶ meter (m), we can establish the direct conversion factor without having to convert to and from meters first. Therefore, the exact conversion factor is:
1 millimeter = 1,000 micrometers
To convert from micrometers to millimeters, divide the number of micrometers by 1,000. For example, if you have 3,000 micrometers, divide by 1,000 to get 3 millimeters.
