How to Convert Inches to Decimal
Separate Whole and Fractional Parts, (e.g., 6 3/8 becomes 6 and 3/8). Convert Fraction to Decimal: Divide the numerator (top number) of the fraction by the denominator (bottom number). For example: Fraction = 3 / 8 = 0.375.
Add Whole Number and Decimal: Add the whole number of inches to the decimal result of the fraction: Whole Number + Decimal = 6 + 0.375 = 6.375
