Formulas

An ordinary room temperature in the Philippines, 26.0°C, in °F? Solution: Using the formula then substitute Example 1

A body temperature of 98.6°F in Celsius? Solution: Using the formula then substitute Example 2

Very cool day in Baguio City, 14.0°C in Kelvin? Solution: Using the formula then substitute Example 3

Problem: Express normal body temperature, 98.6°F, in °C and K. Now, it’s your turn.

Solution The Fahrenheit to Celsius conversion equation may be expressed in this form: To solve for Celsius: °C = (98.6 °F – 32) x 5/9 °C = (66.6) x 5/9 °C = 37.0 To solve for Kelvin: K = °C +273 K = K = 310

 Answer 98.6 °F is equal to 37.0°C and 310 K wew
