Cable

What is a cable?

A cable is a nautical unit of length equal to one tenth of a nautical mile (exactly 185.2 m). It is used in maritime navigation for short-distance descriptions.

Origin of the cable

The cable derives from the historical length of a ship's anchor cable. Standardised at one tenth of an international nautical mile in 1929.

Where it is used

Cables are used in modern maritime navigation when describing short distances between vessels, anchoring depths, and harbor manoeuvres. Common in naval and yachting contexts.

When and where it was developed

Standardised at 1/10 nautical mile by the International Hydrographic Organization in 1929.

Metric / SI

Millimeter

What is a millimeter?

A millimeter is a metric unit of length equal to one thousandth of a meter (1/1000 m). It is the standard small-scale unit in the SI system and is widely used wherever sub-centimeter precision matters.

Origin of the millimeter

The millimeter was defined alongside the meter when France adopted the metric system in 1795, using the standard SI prefix milli- (from Latin mille, "thousand") to denote one-thousandth.

Where it is used

Millimeters are used in engineering drawings, machining, manufacturing, paper sizes, rainfall measurement, and any context where dimensions below one centimeter need to be specified clearly. Most rulers worldwide are marked in millimeters.

When and where it was developed

Adopted in 1795 in France as part of the original metric system; standardized internationally by the Metre Convention in 1875 and confirmed in the SI in 1960.
