## How the conversion works

The relationship is µm = ft × 304,800. 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.

> Foot: Plural is "feet".

## Common questions

### How many micrometers are in one foot?

One foot equals 304,800 micrometers. µm = ft × 304,800.

### How do you convert feet to micrometers?

Use µm = ft × 304,800. So 10 ft is 3,048,000 µm.

### How many feet are in one micrometer?

One micrometer equals 0.000003281 feet, which is the reverse of the conversion above.

### Is there more than one kind of foot?

Plural is "feet".
