Chapter 1, Problem 1.108QP

Interpretation Introduction

Interpretation:

A newborn is $\text{21}\text{in}$ in length and weighs $\text{6}\text{lb}\text{9}\text{oz}$.  The baby has to be described in metric units.

Concept Introduction:

The conversion factor used to convert inch into meters is

  $\begin{array}{l}\text{12}\text{in}\text{=}\text{1}\text{ft;}\text{1}\text{yd}\text{=}\text{3}\text{ft;}\text{1}\text{yd}\text{=}\text{0}\text{.914}\text{m}\\ \text{conversion}\text{factor:}\\ \text{=}\frac{\text{1}\text{ft}}{\text{12}\text{in}}\text{×}\frac{\text{1}\text{yd}}{\text{3}\text{ft}}\text{×}\frac{\text{0}\text{.914}\text{m}}{\text{1}\text{yd}}\end{array}$

The conversion factor used to convert pound into grams is

  $\begin{array}{l}\text{1}\text{lb}\text{=}\text{454}\text{g}\\ \text{conversion}\text{factor:}\\ \text{=}\frac{\text{454}\text{g}}{\text{1}\text{lb}}\end{array}$

The conversion factor used to convert ounce into grams is

  $\begin{array}{l}\text{1}\text{lb}\text{=}\text{16}\text{oz;}\text{1}\text{lb}\text{=}\text{454}\text{g}\\ \text{conversion}\text{factor:}\\ \text{=}\frac{\text{1}\text{lb}}{\text{16}\text{oz}}\text{×}\frac{\text{454}\text{g}}{\text{1}\text{lb}}\end{array}$
