Few people know that Thomas Jefferson gave us our decimal money (10 dimes and 100 pennies)
1) It’s the system 95 percent of the world uses
(It’s not standard in the U.S., Burma, and Liberia)
2) It’s easier to make conversions
(You just move the decimal point right and left)
3) Teaching two measurement systems to children is confusing
4) It’s the language of science
5) It’s the language of medicine
6) Human conversion errors are inevitable
(We lost a Mars orbiter that way and pharmacy mistakes are common)
7) It’s the language of international commerce
8) Many hobbies and sports use the metric system
9) Its use is necessary for travel outside of the United States
10) So we look less foolish and ignorant to the rest of the world
And a few more for good “measure..”
11) Less clutter since you don’t need liquid and dry measuring cups and teaspoons and tablespoons
(Just a scale and liquid measuring cups)
12) It’s much easier to conceptualize 1 gram verses 1/28th of an ounce or 1 milliliter verses 1/29 of a liquid ounce (rounded measures)
13) There are fewer measures to learn. Most people will use meters, liters, and grams verses more than 10 for liquid and dry measures alone
14) It was designed to be easy to learn and use
(In 1790s Europe the literacy rate was around 60 percent)
