1w

1w is a string that can denote different concepts depending on context. The most widely recognized meaning is related to the unit of power. When written as 1 W (or 1w in informal contexts), it stands for one watt, the SI unit of power equal to one joule per second. It is used to label the power ratings of devices, such as light bulbs, motors, and power supplies. In technical and engineering documents, spacing and capitalization are important; the standard symbol is W, and 1 W denotes exactly one watt.

In informal or shorthand contexts, 1w is commonly used to mean one week. This usage appears in scheduling, planning notes, or relative time expressions like "1w ago" in messaging apps and repositories. It is not a formal standard and can vary by platform or locale.

Additionally, 1w may appear as part of codes, identifiers, or filenames, including product model numbers or catalog entries. In such cases the meaning is defined by the supplying organization and should be inferred from context.

Notes: be aware of distinctions between 1w, 1W, and 1 W. The lowercase w is not a standard symbol for the watt and may reflect stylistic or technical constraints in text or filenames. Overall, the precise meaning of 1w depends on where and how it is used.
