Absolute Scale

An ordinary room temperature in the Philippines, 26.0°C, in °F?

Solution: Using the formula

then substitute

A body temperature of 98.6°F in Celsius?

Solution: Using the formula

then substitute

Very cool day in Baguio City, 14.0°C in Kelvin?

Solution: Using the formula

then substitute

Problem:Express normal body temperature, 98.6°F, in °C and K.

SolutionThe 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 +273K = 37.0 + 273K = 310

wew

Answer98.6 °F is equal to 37.0°C and 310 K
