2l

2L, 2l, or 2 L is a designation that appears in several unrelated fields, so its meaning depends on context. Because a lowercase l can resemble the digit 1 or the letter I in some fonts, there is potential for ambiguity when the term is written without clear typographic distinction.

In measurement and everyday labeling, 2 L commonly denotes two liters, a standard unit of volume. This notation appears on product labels, beverage containers, and packaging. In formal writing, spaces or capitalization may vary (2 L, 2 L).

In genetics, especially in Drosophila melanogaster nomenclature, 2L refers to the left arm of the second chromosome. This arm is used in genetic mapping and cytogenetic studies, with researchers referencing loci and genes by their position on 2L within chromosomal maps and genome projects.

In computing and programming, several languages support literal suffixes for type specification. In languages such as C, C++, and Java, a numeric literal followed by an L or l, as in 2L, designates the value 2 as a long integer. The exact rules and case sensitivity vary by language, and in some contexts 2L may be invalid.

In music, 2L is the name of a Norwegian audiophile record label known for high-fidelity releases, including SACD and high-resolution formats. The label publishes recordings across classical and contemporary repertoires and is recognized in audiophile circles for its recording and mastering quality.

Because 2L has multiple uses across domains, the intended meaning is usually clear from the surrounding context.
