Metric Length, Height and Distance. The metre is the standard of length, which is divided into 100 centimetres, also into 1000 millimetres. 1000 metres is the same as 1 kilometre. And we can also see that 10 millimetres is the same as 1 centimetre. These distances can all be abbreviated to 1 or 2 letters for ease of use, especially in writing.
The base unit of length for the metric system and the International System of Units (SI). Defined as the exact distance light travels in an absolute vacuum in 1/299 792 458 of a second. Originally, in 1791, the meter was defined as 1/10 000 000 of the distance between the equater and the North Pole through Paris. Then in 1889 and lasting until 1960 the meter was defined as the exact length of a metal bar kept under certain conditions. In 1960 the definition changed again to be 1 650 763.73 wavelengths of the orange-red emission line in the electromagnetic spectrum of the krypton-86 atom in a vacuum.
