# Definition:Time/Unit/Minute

## Definition

The **minute** is a derived unit of time.

- $1$
**minute**$= 60$ seconds.

### Symbol

The symbol for the **minute** is $\mathrm {min}$.

## Historical Note

The division of the **hour** into $60$ subdivisions originated some undecidable time in the Middle Ages, using the same sexagesimal (base $60$) system that was used to subdivide degrees of angle.

These systems of division of time and angle are the last system of measurements which have not been decimalised.

## Linguistic Note

The word **minute**, in the context of the measurement both of **time** and of **angle**, derives from its initial definition as a **minute part of an hour** or of a **degree of angle**.

In this context the word **minute** (meaning: the aggregation of $60$ **seconds**) is pronounced ** min-it**.

The word **minute** (as used in the phrase **minute part**) is pronounced **my- nyoot** and means

**small**.

So the fact that the two words are spelt identically is not a coincidence.
