Fahrenheit
temperature scale based on measurement system proposed in 1724 by German physicist Gabriel Fahrenheit
- water freezes at 32ºF
- water boils at 212ºF
- 180 degrees of separation between the two points
*at sea level and standard atmospheric pressure
Celsius
scale for measurement of temperature developed by Swedish astronomer Andres Celcius in 1742
- water freezes at 0ºC
- water boils at 100ºC
- used to be called centigrade
*at sea level and standard atmospheric pressure
Celcius to Farenheit Relationships
- Farenheit scale runs from 32 - 212 with a 180 degree separation
- Celcius runs from 0 - 100, a 100 degree separation
- Every 9 degrees of Farenheit = 5 degrees of Celcius (180/100 or 1.80)
Solve for ºF
ºF = (1.80 x ºC) + 32º
Solve for ºC
(ºF - 32º)/1.80 = ºC
