The formula used to convert Celsius temperature (°C)into Fahrenheit temperature (°F) is''

Choose an answer

°C = 9/5(°F -32)

°C = 5/9(°C +32)

°C = 5/9(°F + 32)

°C = 5/9(°F -32)

The formula used to convert Fahrenheit temperature (°F) into celsius temperature (°C) is:

Choose an answer

°F = (9/5 X ° c) + 33

°F = (9/5 X ° c) + 32

°F = 9/5(°F - 32)

°F = 9/5(°F + 32)
