How many inches are in a foot?

There are exactly 12 inches in 1 foot. This is a defining relationship of the imperial system, so the factor of 12 is exact.

What is 5 feet 10 inches in inches?

Multiply the feet by 12 and add the inches: 5 ft 10 in = (5 × 12) + 10 = 70 inches. This is handy for entering a height as a single number, for example before converting to centimetres.

What is 1 foot in inches?

1 foot equals exactly 12 inches. Some handy values: 2 ft = 24 in, 3 ft = 36 in (also 1 yard) and 6 ft = 72 in. The converter shows the exact inch value for any feet figure you enter.

When should I convert feet to inches?

It is common for heights, lumber and board lengths, and room or furniture dimensions where a measurement in feet is easier to work with in inches — for example when a cut list or a tool is marked in inches.

Can this tool convert inches back to feet?

ABOUT LENGTH UNITS

Length is measured against the metre, the SI base unit, defined by the speed of light. Every unit here is stored as its exact number of metres, so a conversion is simply the input turned into metres and then into the target unit. The metric prefixes run the full modern range — from the quectometre (10⁻³⁰ m) to the quettametre (10³⁰ m), including the ronna and quetta prefixes added in 2022. The imperial and US units use their exact international definitions (an inch is exactly 2.54 cm), while astronomical units such as the light-year, astronomical unit and parsec, and sub-atomic scales like the ångström, Bohr radius and Planck length, extend the range in both directions. Historical and regional units — cubits, ells, versts, the Scandinavian mile — and playful ones like the smoot use common modern equivalents and can vary by source.
