Celsius Formula

Celsius Formula

The degree Celsius or just Celsius, also known as the scale centigrade, is a scale used to measure temperature in the International System of Units (SI). Before being renamed to honor Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps. There are three scales to measure the temperature: Celsius, Kelvin and Fahrenheit.

kelvin = celsius + 273.15

The equation is written

K = C + 273.15

We have:

K = kelvin

C = Celsius

from Celsius to Fahrenheit

Fahrenheit = Celsius*9/5 + 32

The equation is written

F = C *9/5 + 32

We have:

F = Fahrenheit

C = Celsius

Celsius Questions:

1) How much are 60 oC in K?

Answer: We will transform the temperature measurement from Celsius to Kelvin using the first formula, where C = 60 oC.

K = C+ 273.15

K = 60 oC + 273.15

K = 333.15 K.

2) How much are 85 oC in oF?

Answer: We will transform the temperature measurement from Celsius to Kelvin using the second formula, where C = 85 oC.

F = C *9/5 + 32

F = 85 oC *9/5+32

F = 185 oF.
