Chapter 1, Problem 1.81QP

Interpretation Introduction

Interpretation: For the given temperature in Fahrenheit, it should be expressed in degree Celsius of percentage of error expected from thermometer in measuring person’s body temperature of 38.9 degree C.

Concept introduction:

• Conversional formula from Celsius to Fahrenheit,

${\text{F}}^{\text{o}}\text{=}\left({}^{\text{o}}\text{C×}\frac{{\text{9}}^{\text{o}}\text{F}}{{\text{5}}^{\text{o}}\text{C}}\right)\text{+}{\text{32F}}^{\text{o}}$

• Conversional formula from Fahrenheit to Celsius

${}^{\text{o}}\text{C}=({\text{F}}^{\text{o}}-{\text{32F}}^{\text{o}})\times \frac{{\text{5}}^{\text{o}}\text{C}}{{\text{9}}^{\text{o}}\text{F}}$

• Conversional formula from Celsius to Kelvin,

$\text{K}\text{=}{}^{\circ }\text{C}\text{+}\text{273}\text{.15}$

• To find the $\text{percentage of error =}\frac{\left[\text{true value-experiment value}\right]}{\text{true value}}\text{×100\%}$
