Convert one light-nanosecond to millimeters

Explanation

To convert one light-nanosecond to millimeters all we need is to know the conversion factor and we are done. Luckily, we can compute that factor using the units' definitions below.

The result is that there are approximately 299.7925 millimeters in 1 light-nanosecond.

Formula

1 lns ≈ 299.7925 mm

symbol	lns

The light-nanosecond (lns) is a unit of length.

The unit was popularized by the mathematician and computer scientist Grace Hopper. She distributed pieces of plastic coated wire roughly 30 centimeters long to visually show why satellite communications were "slow" and later how smaller computer would be faster (at the time, powerfull computers were the size of a room).

Definition of the light-nanosecond

A light-nanosecond is the distance that light travels in vacuum in one nanosecond.

Some Facts

An acorn between 10 and 60 millimeters in length has the potential to become an oak tree tens of meters tall.
The largest species of praying mantises can measure up to 200 millimeters or roughly the length between the thumb and the middle finger of an adult.

Prefix

milli

10^-3

The prefix milli- comes from the Latin mille meaning a thousand. The associated multiplicative factor is 0.001 or 10^-3.

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.
