Chapter 1, Problem 56P

Interpretation Introduction

(a)

Interpretation:

The mass in pounds of the individual is to be calculated.

Concept introduction:

The relationship between kilograms and pounds is as follows:

  $2.21\text{lb}=1\text{kg}$

The conversion can be done as follows:

  $\left(\text{Given unit}\right)\left(\text{Conversion factor}\right)=\text{Desired unit}$

Interpretation Introduction

(b)

Interpretation:

The number of milliliters contained in the average human body is to be calculated.

Concept introduction:

The relationship between pint and liters is as follows:

  $1\text{L}=1.759\text{ pt}$

The relationship milliliters and liters as follows:

  $1\text{L}=1000\text{ mL}$

The conversion can be done as follows:

  $\left(\text{Given unit}\right)\left(\text{Conversion factor}\right)=\text{Desired unit}$

Interpretation Introduction

(c)

Interpretation:

The temperature of the patient body in Celsius is to be calculated.

Concept introduction:

The S.I unit of temperature is Kelvin $\left(\text{K}\right)$ . One unit can be converted into another using the proper conversion factor.

The conversion factor to convert temperature from degree Celsius to Kelvin is,

  $T\left(\text{K}\right)=T\left(\text{°C}\right)+273.15$

The conversion factor to convert temperature from degree Celsius to Fahrenheit is,

  $T\left(\text{°F}\right)=\frac{9}{5}T\left(°\text{C}\right)+32$ ...... (1)
