Decimal to fraction conversion is the process of converting a decimal number to its nearest fractional equivalent, commonly used in measurements for inches. This calculator also provides millimeter conversions.
The calculator uses the following process:
Where:
For millimeter conversion: The decimal value is multiplied by 25.4 (inches to mm conversion factor).
Details: Precise conversion between decimal and fractional measurements is essential in fields like engineering, construction, and manufacturing where imperial measurements are still widely used.
Tips: Enter the decimal value, select whether you want to convert to inches fraction or millimeters, and choose your desired precision. The calculator will provide the converted value.
Q1: Why are there different precision options?
A: Different applications require different levels of precision. Construction might use 1/16", while machining might require 1/64" precision.
Q2: How accurate is the conversion?
A: The conversion is mathematically precise for the selected denominator, though real-world measurements may have additional tolerances.
Q3: Can I convert fractions back to decimals?
A: Yes, by dividing the numerator by the denominator (e.g., 3/4" = 0.75").
Q4: Why is 25.4 used for mm conversion?
A: 1 inch is exactly 25.4 millimeters by international agreement since 1959.
Q5: What about very large decimal values?
A: The calculator handles whole numbers and fractions separately for clearer presentation (e.g., 2.375 becomes 2 3/8).
