Usage notes
- The litre is not an SI unit but is accepted for use with SI units. The official SI symbols are the capital or lower-case roman L. The script symbol ℓ, while not officially sanctioned, was sometimes used in non-technical contexts to prevent the lower-case roman l from being confused with 1, the number one.
