Feet to Centimeters
Convert foot to centimeter instantly — type a value and read the result, with the exact formula shown.
Example
1 ft = 30.48 cm, 5 ft = 152.4 cm, 10 ft = 304.8 cm.
How it works
Centimeter = Foot × 30.48. Every value is converted through a single meter base unit using internationally defined conversion factors, so any from/to pair stays consistent.
Good to know
Converting feet to centimeters is one of the most common cross-system measurements people make, usually when a height given in feet needs to fit a metric form — a passport application, a gym profile, a sports roster, or a medical chart that asks for centimeters. It also shows up constantly in online shopping, where furniture, doorways, TVs, and curtains are listed in centimeters but you only know the room in feet.
The foot is an imperial and US-customary unit with roots in the literal length of a human foot, later standardized so that exactly 12 inches make a foot. The centimeter is metric, defined as one-hundredth of a meter, the SI base unit of length. The two systems were permanently bridged in 1959 when the international yard-and-pound agreement fixed one inch at exactly 2.54 cm, which makes one foot exactly 30.48 cm — not an approximation, but a defined value.
For quick mental math, treat one foot as roughly 30 cm and you will be within about 1.6% — close enough to picture a 6-foot person as a little over 180 cm. To sharpen it, remember that every foot adds an extra half-centimeter beyond 30, so 6 ft is 180 + 3 = 183 cm. A handy benchmark: a standard interior doorway around 6 ft 8 in is almost exactly 203 cm.
The most common mistake is converting heights written as feet-and-inches in one step. A value like 5 ft 9 in is not 5.9 ft; you must first turn the inches into a fraction of a foot (9 ÷ 12 = 0.75), giving 5.75 ft, then multiply by 30.48 to get about 175.3 cm. Multiplying the whole "5.9" by 30.48 produces an answer that is several centimeters too tall.
