Système International d’Unités (SI units)
Born: 1548 in Bruges, Flanders ( now Holland)
Died: 1620 in Hague or Leiden
This is a 34-page book published by the Metric Association which tells about metric units and their symbols and how to use them correctly.
This book is made up of an introduction, four chapters, followed by four appendixes and an index all dedicated to the SI system.
Based on the 1954 CGPM and the 1958 CIPM recommendation, the six base units are given the name "Systeme International d'Unités.”
As the SI, they also did away with the older cgs units such as erg, dyne, and calorie. They said these units should only be used if necessary.
METER:A little longer than a yd. (about 1.1 yds.)
LITER:A little larger than a qt. (about 1.06 qts.)
GRAM:A little more than the weight of a paper clip
(to be used with basic units) For Example:
milli: one-thousandth (0.001) 1000mm = 1m
centi: one-hundredth (0.01) 100cm = 1m
kilo: one-thousand times (1,000) 1000m = 1km
millimeter: 0.001m diameter of a paper clip wire
centimeter: 0.01m a little more than the width of a paper clip
kilometer: 1000m somewhat further than ½ mile
(about 0.6 mile)
kilogram: 1000g a little more than 2lbs. (about 2.2lbs)
milliliter: 0.001L five of them make a teaspoon
hectare: about 2 ½ acres
metric ton: about one tone
