Glossary » Units » Length » Ell
Ell is a unit in the category of Length. It is also known as ells. This unit is commonly used in the UK, US unit systems. Ell has a dimension of L where L is length. It can be converted to the corresponding standard SI unit m by multiplying its value by a factor of 1.143.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).
