Measurement – Temperature
Temperature is defined to check how much the object is hot or cold.
There are two units to define the temperature:
For normal body, temperature is = 37°C = 98.6°F
Where, C = Celsius and F = Fahrenheit
Relation between Celsius and Fahrenheit:
This formula will be used in most of the questions of measurement of temperature where we need to convert C into F or vice versa.
Example 1: Convert 20°C to Fahrenheit.
Solution: We know that,
Therefore, Temperature in °F = = 36 + 32 = 68°F
Example 2: Convert 37°F into Celsius.
Solution: We know that,
Therefore = 2.78°C
