Convert Meters to Thou
1 meter is 39,370.08 thou. One meter is exactly 39370.0787402 thou.
One meter is 39370.079 thou. To convert meters to thou, multiply by 39370.079; to go the other way, divide by 39370.079 or multiply by 2.5400 × 10^-5. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST. The SI base unit, defined since 1983 by the distance light travels in 1/299,792,458 of a second.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: metres to thou is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert meters to thou? The converter and the working
- 1.Take the measurement in meters.
- 2.Multiply by 39370.079 — that is how many thou fit in one meter.
- 3.To go back the other way, divide by 39370.079, or multiply by 2.5400 × 10^-5.
Worked example: 25 meters to thou
- Formula
- m × 39370.079 = thou
- Arithmetic
- 25 × 39370.079 = 984,251.97 thou
- Answer
- 25 m = 984,251.97 thou
The factor is rounded for display; the figure above is computed from the full value.

What is a meter?
The SI base unit, defined since 1983 by the distance light travels in 1/299,792,458 of a second.
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 meter?
One meter is 39370.079 thou. Going the other way, one thou is 2.5400 × 10^-5 meters. 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 meter.
