📐 Understanding Inch Fractions
Inches are commonly divided into fractions with denominators that are powers of 2:
- • Halves: 1/2"
- • Quarters: 1/4", 3/4"
- • Eighths: 1/8", 3/8", 5/8", 7/8"
- • Sixteenths: 1/16", 3/16", 5/16", etc.
- • Thirty-seconds and sixty-fourths for precision work
🌟 Practical Applications
Woodworking
- • Measuring lumber thickness
- • Setting saw blade depth
- • Drilling precise holes
Engineering
- • Technical drawings
- • Machine part specifications
- • Tolerance calculations
💡 Quick Reference
Common Equivalents:
- 1/2" = 0.5000" = 12.700 mm
- 1/4" = 0.2500" = 6.350 mm
- 1/8" = 0.1250" = 3.175 mm
- 1/16" = 0.0625" = 1.588 mm
Conversion Factor:
- 1 inch = 25.4 mm (exactly)
- To convert: multiply inches by 25.4
- From mm: divide by 25.4
⚠️ Important Notes
- • Always simplify fractions to lowest terms
- • Be careful with precision - more decimal places mean more accuracy
- • In woodworking, 1/16" is often the practical limit
- • For machining, 1/64" or decimal inches are common
- • Remember: measuring twice prevents costly mistakes
