What is a meter?
The SI base unit of length, defined by the distance light travels in 1/299,792,458 of a second.
What is a micrometer?
A millionth of a metre, also called a micron. Human hair is roughly 70 µm across.
The formula
µm = m × 1,000,000
Every result on this page comes from this formula. Nothing is rounded until the final display, so figures match a spreadsheet to the cent.

Meters to Micrometers — frequently asked questions
How many micrometers are in a meter?
One meter equals 1,000,000 µm. µm = m × 1,000,000
What is the formula to convert meters to micrometers?
The formula is µm = m × 1,000,000. It is an exact definition rather than an approximation, so the conversion never drifts no matter how large the number.
How do I convert micrometers back to meters?
Divide instead of multiplying: one micrometer is 1e-06 m. The reverse converter is linked in the related tools list.
Is this conversion exact?
Yes. Both units are defined against the same base unit by international agreement, so the factor is exact — any rounding you see is only in the display, which you can widen by entering more decimal places.
