There are 453.59 grams per pound. An infant weighs 6,577 grams. What is the weight of the infant in pounds and ounces?
14 lb 8 oz
6577 grams/453.59 grams per pound = 14.5 pounds. There are 16 oz. per pound, so .5 pounds = 8 oz.
98.6 degrees Fahrenheit is what temperature in Celsius?

A patient on a clear diet consumes the following for the day
440 mL
The patients total intake is calculated first by converting everything to ounces: 2 pints of water x 16 oz per pint = 32 oz.; 32 oz. water + 8 oz. coffee + 8 oz. soup = 48 oz. To convert ounces to milliliters (mL) multiply by 30 oz./milliliter. 48 oz. x 30 ox/mL = 1440 mL. Therefore the deficit in milliliters is 1440-1000 = 440 mL
A sample contains 2/3 oz of liquid. How many milliliters (mL) is this?
20 mL
To convert oz. to mL, multiply by 30 oz/mL. 2/3 x 30 = 60/3 = 20 mL
How many meters in a kilometer?
1000
How many grams are in a kilogram?
1000
10 kilograms is equivalent to how many pounds?

To convert kilograms to pounds, multiply by 2.2 pounds/kilogram. 10 x 2.2 = 22
Instructions require you to dilute a powder in 3 quarts of water. You only have a container that is marked in liters. How many liters would you use to dilute the powder?
2.88 liters
1 quart = 32 oz. Therefore 3 quarts = 96 oz. There are 30 milliliters per oz, so 96 oz = 2,880 milliliters. There are 1000 milliliters per liter, so 2,880 mL = 2.88 liters
How many milliliters are in 1 liter?
1000
A man’s waist measurement is 88.9 centimeters. What is his waist in inches?
