Forms and variants

"ℓ" redirects here. For the azimuthal quantum number, see azimuthal quantum number.

In some fonts, the lowercase letter ⟨l⟩ may be difficult to distinguish from the digit one, ⟨1⟩, or an uppercase letter ⟨I⟩. In recent times, many new fonts have curved the lowercase form to the right, and it is increasingly common, especially on European road signs and advertisements. A more modern version based on the handwritten letter-like ⟨ℓ⟩ is sometimes used in mathematics and elsewhere. In Japan, for example, this is the symbol for the liter. Its LaTeX command is \ell, its codepoint is U+2113, and its numeric character reference is "ℓ".
