Inches to micrometers
1 inch in micrometers
1 in = 25,400 µm
µm = in × 25,400
To convert inches to micrometers, multiply by 25,400. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works
The relationship is µm = in × 25,400. Both units measure length, so the conversion is a fixed factor that never changes. The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two.
Common questions
- How many micrometers are in one inch?
- One inch equals 25,400 micrometers. µm = in × 25,400.
- How do you convert inches to micrometers?
- Use µm = in × 25,400. So 10 in is 254,000 µm.
- How many inches are in one micrometer?
- One micrometer equals 0.00003937 inches, which is the reverse of the conversion above.
