Question

How do you convert 850F to Celsius?

Answer 1

Celsius and Fahrenheit are the units for measuring temperature.
The degree Celsius is a unit of temperature on the Celsius scale.
Fahrenheit is a temperature scale that bases the boiling point of water at 212 and the freezing point at 32.

Complete step by step answer:
First we will discuss Fahrenheit and Celsius scales in more detail and then we will do the calculation part of the problem.
Fahrenheit is the basis of temperature scale is now usually defined by two fixed points; the temperature at which pure water freezes into ice is 320 F and the boiling point of water is defined to be 2120F, both at standard atmospheric conditions.
Celsius unit of temperature usually called a centigrade scale. At zero degree Centigrade water freezes and at 1000 Celsius water starts boiling. The scale of Celsius is divided into 100 degrees intervals.
Conversion between Celsius and Fahrenheit scale is done by the following conversion;
$F = (\dfrac{9}{5} \times C) + 32$ (F is the Fahrenheit, C is the Celsius)
Now, we will do the calculation part of the problem.
$\Rightarrow 85 = (\dfrac{9}{5} \times C) + 32$ (We have substituted the value of Fahrenheit scale)
$\Rightarrow 85 - 32 = \dfrac{9}{5} \times C$ (Rearranged the terms)
$\Rightarrow 53 \times 5 = 9C$ (We have shifted 5 on the LHS)
$\Rightarrow C = \dfrac{{265}}{9} = 29.44$ (Final value)
$\Rightarrow {29.44^0}C$ Celsius scale.

Note: Like Fahrenheit and Celsius other two temperature measuring units are Kelvin and Rankine. Rankine is an absolute scale that uses absolute zero as the starting point. Kelvin is the base unit of temperature, Kelvin is often used as a measure of the color temperature of light sources.
