Frequently Asked Questions
Should I use decimal or fractional inches?
Use decimal inches (2.5") for precision work and engineering. Use fractional inches (1/2", 3/8") for traditional woodworking and construction where tape measures and rulers use fractions.
What fraction precision should I choose?
For most woodworking and DIY, 1/16" is standard. For fine woodworking or precision work, use 1/32". For rough framing or general construction, 1/8" may be sufficient.
