Why use a foot and inch calculator?
A foot and inch calculator removes guesswork from everyday measurement problems.

Many people search for a feet to inches calculator, inches to feet conversion, or ft in to cm converter. This page combines all of those in one place, so you do not need multiple tools.
How this conversion works
Core formulas
- 1 foot = 12 inches
- 1 inch = 2.54 centimeters
- 1 meter = 100 centimeters
- Total inches = (feet × 12) + inches
Once total inches are known, conversions are straightforward. For example, centimeters are calculated as total inches × 2.54, and meters are centimeters ÷ 100.
Normalization of feet and inches
Sometimes measurements are entered as 5 feet 14 inches. That is valid in practice, but many people prefer standard form. A calculator normalizes this into 6 feet 2 inches, which is easier to read and compare.
Practical examples
Example 1: Height conversion
If height is 5 ft 9 in:
- Total inches = 5 × 12 + 9 = 69 in
- Centimeters = 69 × 2.54 = 175.26 cm
- Meters = 1.7526 m
Example 2: Convert 72 inches
72 inches is exactly 6 feet 0 inches. In metric, it equals 182.88 cm or 1.8288 m.
Example 3: Convert 180 cm
180 cm converts to about 70.87 inches, which is 5 feet 10.87 inches.
