30kilometer

30kilometer is a term that may refer to the distance of thirty kilometers, written without a space or punctuation in certain contexts. It is not an official unit or term in the metric system; the standard English form is thirty kilometers, abbreviated as 30 km (or 30 kilometre in British spelling).

The concatenated form commonly appears in branding, file names, domain names, software identifiers, and data schemas where spaces are discouraged or impractical. In typography and information design, 30kilometer may be used as a compact label. In datasets, a field or variable named 30kilometer typically represents a distance value of 30 kilometers.

Despite its appearance, the term is not intended for formal measurement or technical specification. When the distance is relevant in formal writing or publication, the preferred notation is 30 km or 30 kilometre, depending on the regional variant of English.

Notes on usage vary by context. In programming and data management, such concatenated forms can serve as identifiers, keys, or slugs, but they do not change the underlying quantity, which remains 30 kilometers.
