About both units

From

Meter

The meter is the base SI unit of length. It was first defined in 1793 as one ten-millionth of the distance from the equator to the North Pole through Paris. Today it is defined as the distance light travels in vacuum in 1/299,792,458 of a second — a definition tied directly to the universal speed of light. The meter is the foundation of the metric system used by 95% of the world.

Real-world: A standard door is about 2 metres tall. An Olympic swimming pool is exactly 50 metres long. The Eiffel Tower is 330 metres tall.

Kilometer

The kilometer equals 1000 meters and is the standard unit for road distances in almost every country except the US and UK. Speed limits in Europe, Asia, Australia and most of Africa are given in km/h. A kilometer is roughly 1250 adult walking steps and takes about 12 minutes on foot.

Real-world: London to Paris by Eurostar is 344 km. A full marathon is 42.195 km. Most European motorway speed limits are 120–130 km/h.

Tips & common mistakes

Quick tips

1 metre ≈ 3.28 feet — multiply by 3.28 for a quick foot conversion.
The height of an average adult is 1.6 to 1.8 metres — useful for sanity-checking lengths.
For very small or very large quantities use prefixes: 1 km = 1000 m, 1 mm = 0.001 m.

Avoid these

Confusing square metres (area) with metres (length). A 20 m² room is not 20 m long.
Using 3.3 instead of 3.2808 when converting to feet — the error grows on long distances.
Writing "meter" when you mean "metre" in British English, or vice versa. Both are accepted but follow one convention per document.
