How many thou are in 1 foot?

One foot contains exactly 12,000 thou. Since 1 foot = 12 inches and 1 inch = 1,000 thou, multiply 12 by 1,000.

How do I convert feet to thou?

Multiply the foot value by 12,000. For example, 0.5 feet = 6,000 thou (6 inches).

When would I need feet in thou?

In manufacturing when overall part dimensions (feet) must be compared with coating thickness, wire diameter, or machining tolerances (thou). Engineering drawings may mix both units.

Good to Know About Feet to Thou Conversion

American machinists think in thou for precision work and feet for part size. A machinist might say 'a 2-foot bracket with a 5-thou tolerance.' Both units live on the same shop floor but serve different precision levels.

Feet to Thou: What You Need to Know

A foot of material is 12,000 thou. A standard PCB at 62 thou thick is 0.00517 feet. Paint thickness at 2-4 thou is 0.000167-0.000333 feet. In American manufacturing, large part dimensions are in feet while fine tolerances are in thou. Both coexist on the same blueprint.

Non-Frequently Asked Questions About Feet to Thou

Questions nobody should ask - but someone did.

A standard hardwood floorboard is about 3/4 inch = 750 thou thick. In feet, that is 0.0625 feet. The floor you walk on is 750 thousandths of an inch thick. This sounds less reassuring than '3/4 inch,' which is why carpenters do not use thou.
A human hair is about 3 thou (0.003 inches = 0.00025 feet). In feet, a hair is a quarter of a thousandth of a foot. This is why thou exist: to give meaningful numbers to things that are unmeaningfully small in feet.
No. Building codes use feet and inches (US) or millimeters (metric). Thou are for manufacturing tolerances, not construction. A building inspector saying 'your wall is 500 thou too thin' would be saying '0.5 inches,' which would be more useful and less confusing.
