Measuring length in feet but need the result in inches? This free feet to inches calculator gives you an instant, accurate conversion — plus equivalent values in centimeters, meters, and yards — all in one click.

Quick Definition: A feet to inches converter multiplies your foot value by 12 to give the inch equivalent. One foot equals exactly 12 inches. This inch calculator also shows cm, meter, and yard equivalents, making it a complete length conversion tool for everyday and professional use.

How Feet-to-Inches Conversion Works

The foot and inch are both units of length in the US customary and imperial measurement systems. Since there are exactly 12 inches in a foot, converting between them is straightforward multiplication or division.

Feet to Inches formula: Inches = Feet x 12

Inches to Feet formula: Feet = Inches / 12

For example, 50 ft x 12 = 600 inches. The calculator also auto-converts to metric — 50 ft equals 1524 cm and 15.24 meters — handy when switching between imperial and metric systems.

Limitations: This tool works with decimal inputs (e.g., 5.5 ft), not mixed numbers like 5’6″. For that, use the Feet & Inches Calculator which handles mixed number formats directly. Results are rounded to 4 decimal places, so for millimeter-level precision in construction calc work, always verify with a tape measure or ruler.

How to Use This Converter

The tool has two modes, switchable at the top: Feet to Inches and Inches to Feet.

1. Select your direction using the tab toggle at the top of the calculator.
2. Enter your value in the input field (e.g., 5.5 for feet, or 10 for inches).
3. Click Calculate Conversion.
4. Your primary result appears in large text — inches or feet — with equivalent values in centimeters, meters, and yards listed below.
5. Use Reload Calculator to reset, or Print / Share to save your result.
