Conversion Methods

As a healthcare employee, you will be confronted with converting measurements obtained using one system into the equivalents of another system. Let's explore some standard equivalents between the household and metric systems.

Conversion Methods
Measuring Equivalents	Conversion Methods	Examples
2.2 lb = 1 kg	Pounds to kilograms Divide the number of pounds by 2.2	110 lb/2.2 = 50 kg
	Kilograms to pounds Multiply the number of kilograms by 2.2	72 kg x 2.2 = 158 lbs
1 tsp = 5 mL	Teaspoons to milliliters Multiply the number of teaspoons by 5	2 tsp x 5 = 10 mL
1 oz = 30 mL	Ounces to milliliters Multiply the number of ounces by 30	0.5 oz x 30 = 15 mL
1 qt = 1,000 mL	Quarts to milliliters Multiply the number of quarts by 1000	5 qt x 1,000 = 5,000 mL
1 in = 2.54 cm	Inches to centimeters Multiply the number of inches by 2.54	72 in x 2.54 = 180 cm
	Centimeters to inches Divide the number of centimeters by 2.54	220 cm/2.54 = 88 inches
Fahrenheit (F) to Celsius (C)	$LaTeX: \left(^{\circ}F-32\right)\times0.5556$ $\left(^{\circ}F-32\right)\times0.5556$	$LaTeX: \left(98-32\right)\times0.55568=36.7^{\circ}$ $\left(98-32\right)\times0.55568=36.7^{\circ}$
Celsius to Fahrenheit	$LaTeX: \left(^{\circ}C\times1.8\right)+32$ $\left(^{\circ}C\times1.8\right)+32$	$LaTeX: \left(0\times1.8\right)+32=32.0^{\circ}$ $\left(0\times1.8\right)+32=32.0^{\circ}$

To convert meters to inches, move the decimal first and then use the centimeters (cm) to inches (in) formula.

14m = how many inches? 14 meters equals 1400 centimeters, then divide by 2.54 to get 551 inches
