Unit information

Foot

/fʊt/

Symbol: ft
Unit system: Imperial

What is the Foot?

The foot is a unit of length in the imperial unit system and uses the symbol ft.

One foot is exactly equal to 12 inches. It is also exactly equal to 0.3048m. One yard is comprised of three feet.

The foot is just behind the metre in terms of widespread use due to its previous popularity. The US is the only developed country that still uses the foot in preference to the metre.

The UK still uses feet to express human height more than metres.

Light Year

/lʌɪt jɪə,jəː/

Symbol: ly
Unit system: Astronomical System of Units

What is the Light Year?

The light year is a unit of length in the Astronomical system of units. It uses the symbol ly.

Often confused with a unit of time as it contains the word "year", it is actually defined by the International Astronomical Union (IAU) as the amount of distance that light travels in a vacuum in one Julian year (365.25 days).

Using the speed of light (299,792,458 m/s or 'c') and the Julian year (as apposed to the Gregorian year which is 365.2425 days), we can equivalate 1 light year as 9,460,730,472,580,800 metres or ≈ 9.46 trillion kilometres.
