Converting feet to inches is one of the simplest and most frequently used unit conversions within the imperial system. Since there are exactly 12 inches in every foot, simply multiply the foot value by 12. Use the converter above for instant results, or follow the formula and examples below.

Foot (ft) is an imperial and US customary unit of length equal to exactly 12 inches or 30.48 centimeters. Its origins date back to the length of a human foot used as a natural reference across ancient civilizations. Today, one foot is precisely defined by international agreement as 0.3048 meters. The foot is the standard unit for measuring human height in the United States, ceiling and room heights in construction, altitude in aviation globally, and terrain elevation in surveying and mapping. One foot is roughly the length of a standard 30 cm school ruler.
Inch (in) is an imperial and US customary unit equal to exactly 1/12th of a foot or 2.54 centimeters. Historically based on the width of a human thumb, the inch is defined today as exactly 25.4 millimeters by international agreement. It is widely used for measuring screen sizes (TV, monitor, smartphone diagonals), pipe diameters, screw and bolt sizes, tire widths, and small product dimensions across the US, UK, and Canada. One inch is roughly the width of an adult thumb at its widest point.
| Feet (ft) | Inches (in) | Common Reference |
|---|---|---|
| 1 ft | 12 in | Standard school ruler length |
| 2 ft | 24 in | Typical kitchen countertop depth |
| 3 ft | 36 in | 1 yard / standard door handle height |
| 4 ft | 48 in | Height of an average 7-year-old child |
| 5 ft | 60 in | Average adult female height (US) |
| 5 ft 9 in | 69 in | Average adult male height globally |
| 6 ft | 72 in | Tall adult male reference height |
| 8 ft | 96 in | Standard ceiling height in homes |
| 10 ft | 120 in | Basketball hoop regulation height |
There are exactly 12 inches in one foot. So 1 ft = 12 in. This is one of the most fundamental relationships in the imperial measurement system.
The formula is: in = ft × 12. Multiply any foot value by 12 to get the equivalent length in inches.
5 ft = 60 inches. This is a commonly referenced height conversion — 5 feet equals exactly five dozen inches.
6 ft = 72 inches. Six feet is often used as a benchmark for a tall adult and equals exactly 72 inches or 182.88 centimeters.
Multiply the feet by 12 and add the remaining inches. For example, 5 ft 4 in = (5 × 12) + 4 = 60 + 4 = 64 inches total.
A foot is larger. One foot equals 12 inches — so a foot is twelve times the size of a single inch.
100 inches = 8 feet and 4 inches (since 8 × 12 = 96, and 100 − 96 = 4). To convert inches back to feet, divide by 12 to get the feet, and the remainder is the leftover inches.
