What sciences system is a system of measurement based on the number 10?

Answer 1

SI (also known as the "metric system").

This system was promulgated during the French Revolution, and remains today.

However, a "system of measurement based on the number 10" was first proposed by Thomas Jefferson (before he went to France to represent the new nation), and it was his influence that undobtedly led to the creation and adoption of "System Internationale" (SI). Jefferson's decimal system redefined the "foot" as having ten "inches" and the "pound" as having ten "ounces, but it was not adopted universally.

Jefferson was more successful in getting the United States of America to adopt a system of coinage and currency based on the number 10 -- with the "disme" (later spelled as "dime"), the cent and the "mill" as decimal fractions of a dollar (valued one ounce of silver), and the Eagle as the ten dollars (or one half-ounce of gold). Eventually, variants of Jefferson's 10-based system was adopted for currency denominations by every nation on earth -- including England, which finally discarded its own system (with 4 farthings per pence, twelve pence per shilling, 20 shilling per pound, etc.) in favor of its current, Jeffersonian system, a few centuries later.

Nowadays, SI is used in most scientific calculations (rather than 16 ounces per pound, 32 ounces per quart, etc. and silly units such as the "poundal" and the "slug"), but there is still contention between "MKS" (Meters, Kilograms, Seconds) and "cgs" (centimeters, grams, seconds). Conversions of values between "cgs" and MKS' involve multiplication by powers of ten, but there is . Unfortunately, this has led to duplicate SI values for the same quantities, such as Newtons and ergs (for energy), etc. and (because one hour is 3600 seconds) some time-based conversions such as: 1 kilowatt-hour is equivalent to 3,600,000 joules.
