Is this easy? Or LOGICAL?
A foot 12 inches? A yard 3 feet? The imperial measurement system is absurd and the propagation of it in K-12 education is even more ridiculous. The Metric System is the most commonly used measurement system in the world and in the scientific community. The metric system uses the units in the following chart for measurement.
| Unit | What it Measures |
|---|---|
| Meters | Distance |
| Liters | Volume |
| Grams | Mass |
| Second | Time |
| Kelvin | Temperature |
Part I of a simple review…
Today we do temperature.
Celcius is also often used because of its easy conversion to and from Kelvin. Kelvin is the unit that is used in most calculations in Chemistry.Fahrenheit is unfortunately the most used scale in the U.S.
Fahrenheit, Celcius, and Kelvin
- If you subtract 32 from the Fahrenheit temperature and multiply by 5/9 (or divide by 1.8 ) then it will convert to Celcius temperature.
- If you multiply the Celcius temperature by 9/5 (or 1.8 ) then add 32 it will give you the Fahrenheit temperature.
- Adding 273 to Celcius will give Kelvin, and subtracting 273 from Kelvin you will get Celcius.
