📚 Measurement Conversion Tips
Precision Matters
For critical measurements, always specify your required decimal places to avoid rounding errors.
Fraction to Decimal
Convert fractions by dividing numerator by denominator (3/4 = 3 ÷ 4 = 0.75).
Architectural Scales
In architectural drawings, 1/8" or 1/4" scales are common - convert these to decimals for CAD work.
Machining Tolerances
Precision machining often requires measurements to 0.0001" (one ten-thousandth of an inch).
Digital Tools
Use this calculator to quickly convert measurements for CNC programming or 3D modeling.
Documentation
Always record both fractional and decimal equivalents for clarity in technical documents.
Note: This calculator provides precise conversions between fractional inches and decimal formats. For critical measurements, always verify results with professional measurement tools.
