Convert Feet to Thou
1 foot is 12,000 thou. One foot is exactly 12000 thou.
One foot is 12000 thou. To convert feet to thou, multiply by 12000; to go the other way, divide by 12000 or multiply by 8.3333 × 10^-5. The factor is exact rather than rounded: it follows from NIST. Twelve inches, or exactly 0.3048 meters.

How do you convert feet to thou? The converter and the working
- 1.Take the measurement in feet.
- 2.Multiply by 12000 — that is how many thou fit in one foot.
- 3.To go back the other way, divide by 12000, or multiply by 8.3333 × 10^-5.
Worked example: 25 feet to thou
- Formula
- ft × 12000 = thou
- Arithmetic
- 25 × 12000 = 300,000 thou
- Answer
- 25 ft = 300,000 thou
The factor is exact, so this figure is exact too — only the display is rounded.

What is a foot?
Twelve inches, or exactly 0.3048 meters. Still the working unit of US construction.
What is a thou?
A thousandth of an inch, exactly 25.4 micrometers, and called a mil in American workshops — the same word the metric world uses for a millimeter, which is why a drawing marked "5 mil" is worth checking twice.
How many thou are in a foot?
One foot is 12000 thou, exactly. Going the other way, one thou is 8.3333 × 10^-5 feet. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
Every length unit here
The whole group — 13 units with their symbols and the size of each one in meters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a foot.
