The Metric System
The length of the basic unit, the meter, was kind-of
arbitrarily chosen (one ten-thousandth of a quarter of the Paris
meridian) - but all other units of the metric system of weights and
measures flow from that meter in decimal fashion, multiples of
ten or reductions to one-tenth.
| length | volume | weight | |||
|---|---|---|---|---|---|
| millimeter (mm) | 1mm = 0.001m | milligram (mg) | 1mg = 0.001g | ||
| centimeter (cm) | 1cm = 0.01m | milliliter (ml) | 1ml = 1cm3 = 0.001L |
gram (g) | 1g = weight of 1cm3 water |
| decimeter (dm) | 1dm = 10cm = 0.1m | liter (L) | 1L = 1dm3 = 1000cm3 (10x10x10cm) |
||
| meter (m) | 1m | ||||
| kilometer (km) | 1km = 1000m | kilogram (kg) | 1 kg = 1000g = weight of 1L water | ||

I found the basic numbers in Chambers' Twentieth Century Dictionary and in The Merriam-Webster Dictionary; the Encyclopaedia Britannica provided the meter story.
