Length

µm to m conversion

Convert micrometre (µm) to metre (m). Length units span pipe diameters (mm, inch), plant dimensions (m, ft), and roughness (µm) — mixing metric and imperial is routine.

1 µm = 1e-6 m

Formula

To convert micrometre to metre, multiply the µm value by 1e-6. To go the other way, divide by 1e-6 (or multiply by 1000000).

2	2e-6
5	5e-6
10	1e-5
25	2.5e-5
50	5e-5
100	1e-4

500	0.0005
1000	0.001

Used in practice

Pipe sizes are labelled in inches (NPS) but calculated in mm; equipment layouts mix metres and feet.

Velocity scales with the inverse square of diameter, so a small length error compounds quickly in flow calculations.

Worked example. A length of 100000 µm is 0.1 m.

Frequently asked questions

How do you convert micrometre to metre?

Multiply the value in µm by 1e-6 to get m. For example, 10 µm = 1e-5 m.

What is 1 µm in m?

1 µm equals 1e-6 m.
