Inches to Feet+Inches Converter (All Length Units)

Inches to Feet + Inches – Clean Split Method

Core idea: A total inch value becomes whole feet plus leftover inches. Because 12 in = 1 ft, you just divide by 12: the whole number part is feet, the remainder is the inch part. No approximation—pure integer division + remainder.

Formulas

• feet = floor(totalInches ÷ 12)
• inches = totalInches mod 12
• Decimal feet version: decimalFt = totalInches ÷ 12
• Check: feet × 12 + inches = totalInches
• To yards (optional cross-unit): yd = totalInches ÷ 36
• To centimeters: cm = totalInches × 2.54 (exact)

Quick Values (Common Splits)

Worked Example

Example: Convert 74 inches.
Feet = floor(74 ÷ 12) = floor(6.1666…) = 6 ft.
Remainder inches = 74 − (6 × 12) = 74 − 72 = 2 in.
Result: 74 in = 6 ft 2 in. Decimal check: 74 ÷ 12 = 6.16667 ft → 0.16667 × 12 ≈ 2 in.

Where Used

• Human height notation (e.g., 5 ft 11 in).
• Building materials (board lengths given in total inches, converted for layout plans).
• Furniture + appliance specs blending decimal feet and feet+inches.

Accuracy & Tips

• Always separate integer and fractional parts before rounding: avoid rounding the decimal feet until after extracting whole feet.
• If you begin with fractional inches: convert to decimal inches first (e.g., 5 3/8 in = 5.375 in).
• Verification: recombine feet × 12 + inches to confirm the original total.

FAQ

• Why use feet + inches instead of decimal feet? Feet+inches matches tape measures and practical cutting increments.
• Can leftover inches be fractional? Yes—just keep precision (e.g., 2.5 in) or express as a fraction (2 1/2 in).
• How to reverse? Total inches = feet × 12 + inches.
