What is 89 Fahrenheit in Celsius?

Hint: Here, this question belongs to conversion topic that is we have to convert the unit from one form to other here we have to convert the unit Fahrenheit to the unit Celsius by using a conversional formula \[C = \dfrac{{F - 32}}{{1.8}}\], where \[F\] is the temperature in Fahrenheit and \[C\] its equivalent in Celsius. On substituting the formula and by further simplification using a basic mathematical operation to get the required solution.

Complete step by step solution:
Conversion of Units is a multi-step process that converts units of measurement for the same quantity. It includes division or multiplication by a numerical factor or rounding off the significant digits.
The Fahrenheit and Celsius are the units to measure the Temperature.
A measure of the warmth or coldness of an object or substance with reference to some standard value.
The most common used units of temperature are the Celsius, the Fahrenheit and the kelvin.
Considering the given question, we have to convert \[89\] Fahrenheit (\[F\]) to Celsius \[\left( C \right)\].
To Convert Temperature from Fahrenheit to Celsius. First, we need the formula for converting Fahrenheit (\[F\]) to Celsius \[\left( C \right)\]:
\[ \Rightarrow \,\,C = \dfrac{{F - 32}}{{\left( {\dfrac{9}{5}} \right)}}\]
\[ \Rightarrow \,\,C = \dfrac{{F - 32}}{{1.8}}\]
On substitute the given Fahrenheit value of temperature:
\[ \Rightarrow \,\,C = \dfrac{{89 - 32}}{{1.8}}\]
\[ \Rightarrow \,\,C = \dfrac{{57}}{{1.8}}\]
On simplification, we get
\[ \Rightarrow \,\,C = 31.6666667\]
Hence, Temperature \[89\,F = 31.6666667\,C\].

Note:
We have different units for solid quantity, liquid quantity and gaseous quantity. Every quantity has a measurement unit from the low quantity to the high quantity. While converting the unit of a quantity from one form to another form we have standard value. By multiplying or dividing we can convert the unit of the quantity. We have a different system of measurement of a quantity.
