A temperature of 20 degree Celsius is equal to 68 degree Fahrenheit temperature. Therefore, option b is correct.
What are temperature units ?Temperature is a physical unit which measures the overall heat of an object. The SI unit of temperature is Kelvin (K) and the commonly used unit is degree Celsius (°C).
Other unit of temperature is Fahrenheit (°F). These units can be interconverted between each other with the specific relation between them.
We know that zero degree Celsius is 32 Fahrenheit . Let T be the temperature in degree Celsius,
then, (T° × 9/5) + 32 = T in °F.
Given, temperature = 20 °C.
This temperature can be converted to °F as follows:
(20 °C × 9/5) + 32 = 68 °F.
Therefore, 20 °C is equal to a temperature of 68 °F.
