How to Use This Converter?
This tool converts fractional inches to decimal inches. You can enter inches in several formats:
Fraction only: 1/4, 3/8, 5/16
Whole number and fraction: 1 1/2, 2 3/4, 5 7/8
Decimal: 0.25, 1.5, 2.75
The converter will automatically calculate the decimal equivalent. This is particularly useful in woodworking, metalworking, engineering, and construction where measurements need to be converted between fractional and decimal formats.
Understanding Fractional Inches
Common Fractions
Inches are typically divided into fractions with denominators of 2, 4, 8, 16, 32, or 64. For example: 1/2" (half inch), 1/4" (quarter inch), 1/8" (eighth inch), 1/16" (sixteenth inch).
Mixed Numbers
Mixed numbers combine whole inches with fractions. For example, '2 3/4' means 2 whole inches plus 3/4 of an inch, which equals 2.75 inches in decimal form.
Simplifying Fractions
When working with fractions, it's helpful to simplify them. For example, 2/4 simplifies to 1/2, and 4/8 also simplifies to 1/2. The decimal equivalent remains the same: 0.5 inches.
Precision in Measurements
Smaller fraction denominators (like 64ths) provide greater precision. For example, 1/64" = 0.015625", which is useful for high-precision machining and engineering applications.
