Convert Thou to Yards
1 thou is 0.00002778 yd. One thou is exactly 0.0000277777777778 yards.
One thou is 2.7778 × 10^-5 yards. To convert thou to yards, multiply by 2.7778 × 10^-5; to go the other way, divide by 2.7778 × 10^-5 or multiply by 36000. 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.

Factors are entered by hand from NIST rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert thou to yards? The converter and the working
- 1.Take the measurement in thou.
- 2.Multiply by 2.7778 × 10^-5 — that is how many yards fit in one thou.
- 3.To go back the other way, divide by 2.7778 × 10^-5, or multiply by 36000.
Worked example: 25 thou to yards
- Formula
- thou × 2.7778 × 10^-5 = yd
- Arithmetic
- 25 × 2.7778 × 10^-5 = 0.0006944 yd
- Answer
- 25 thou = 0.0006944 yd
The factor is rounded for display; the figure above is computed from the full value.

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.
What is a yard?
Three feet, or exactly 0.9144 meters. Concrete and fabric are both sold by it.
How many yards are in a thou?
One thou is 2.7778 × 10^-5 yards. Going the other way, one yard is 36000 thou. 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 thou.
