Quart , conversion

A unit conversion starts with an equality between different units. For example, the equivalence between quarts and liters is 1 quart = 0.946 353 L... 

Each equality gives two conversion ratios. The equality between quarts and liters can be rearranged to give two... 

A unit equality may link SI units and non-SI units (1 quart = 0.946353 L), decimally related units (10 c = 1 m ), or base units and derived units (1 L = 10 m ). Some of the more common unit equalities are given on the inside back cover of this text. Examples and treat unit conversions. 

Once we were seated at the restaurant with our quart bottles of Bintang beer in front of us, the conversation began to flow and I started to form an impression of my companions. 

The schmiss on his cheek had turned bright red at this turn of the conversation. I had hoped that there were no further depths of discomfiture to be plumbed in this conversation but I was wrong, for now I saw that he was moving, perhaps under the influence of the third quart of Bintang, from passionate intensity to outright maudlin sentimentality. "No man has ever loved another as Bockermann loved us. We are his kinder, his little birds, ja. When it seemed that there was no hope he inspired us he made us believe in ourselves."... 

Although 1.0 ounce equals 28.35 grams the conversion between U.S. Customary and metric amounts is not equivalent.This is because a liter is slightly more than 32.0 ounces (1.0 quart). This means that it takes 30.0 grams in 1.0 liter to make the same working strength solution as 1.0 ounce in 1.0 quart.Therefore, if you need to convert a U.S. Customary formula into a metric formula, or the other way around, you need to compound the amount of chemical used in order that the percentage of chemistry remains the same in both formulas. 

Again, the SI conversions are more uniform and easier to remember. The older system is even more confusing than it appears here when you consider the fact that English cups, pints, ounces, and quarts are different than the U.S. units with the same names. For example, there are 1.2 U.S. gallons in 1.0 English gallon For this reason alone, American students can probably see the need for a common system. 

The average human body contains 5.2 L of blood. What is this volume in quarts The unit analysis setup for this conversion is below. Identify whether each value in the setup is exact or not. Determine the number of significant figures in each inexact value, calculate the answer, and report it to the correct number of significant figures. 

Mash pale malt in 5 quarts of water. Let rest at 122° for 20 minutes. Increase temperature to 153° and hold until starch conversion. Mash-out at 168° for 5 minutes. Sparge. In a separate step, toast V2 pound of crystal malt in oven at 350° for 10 minutes. Bring crystal malt, toasted malt, and 4 quarts of water to a boil. Strain out grains and add to wort. Bring wort to a boil and add malt extract, and 1 ounce each of Brewer s Gold hops and Cascade hops. Boil for 50 minutes and add Irish moss. Boil for 8 minutes and add 1 ounce of Cascade hops. Boil for 2 more minutes and turn off heat. Cool, transfer to the primary fermenter, and pitch yeast. Ferment for 13 days and prime with % cup com sugar. Bottle. 

Infusion mash — add grains to 11 quarts of 180° water. Stabilize temperature to 156° and allow 1 hour for conversion. Sparge with 11 quarts of 170°-180° water. Bring wort to a boil and add 1 ounce of Cascade hops. Boil for 30 minutes and add V ounce of Chinook hops. Boil another 10 minutes and add V2 ounce of Galena hops. Boil for a final 20 minutes and turn off heat. Add 2 ounces of Saaz hops and let steep. Cool, transfer to primary fermenter, and pitch yeast. When fermentation is complete, bottle with 3A cup com sugar as priming agent. 

Mash-in all grains in 11 quarts of 122° water and hold for 20 minutes. Raise temperature to 145° and hold for 15 minutes. Raise temperature to 158° and hold for 45 minutes, or until starch conversion is complete. Mash-out. Sparge. Bring wort to a boil, add all hops and brown sugar. Boil for 60 minutes and turn off heat. Cool wort and transfer to primary fermenter. Pitch yeast when wort is at room temperature. Ferment for 7 days. Rack to secondary and ferment for another 31 days. Bottle with Vz teaspoon corn sugar per bottle. 

Mash grains in 12 quarts of 153° water treated with gypsum. Hold at 153 for 90 minutes for starch conversion. Mash-out at 168 for 10 minutes. Sparge with 5 gallons sparge water. Add honey and calcium carbonate. Bring to boil and add 1V2 ounces of Northern Brewer hops. Boil 75 minutes and add Irish moss. Boil another 10 minutes and add % ounce of Fuggles hops. Boil a final 5 minutes and turn off heat. Cool, transfer to primaiy fermenter, and pitch yeast. Ferment for 9 days at 68 . Rack to secondary fermenter and ferment another 14 days. Keg and force-carbonate. 

The conversion factor, 4 qt/1 gal, serves as a bridge, or linkage, between the unit that was given (gallons) and the unit that was sought (quarts). 

Carry out the following calculations by using multiple conversion factors (1 quart = 2 pints 1 pound = 16 ounces)... 

As another example of the use of a unit conversion factor, calculate the number of liters of gasoline required to fill a 12-gallon fuel tank, given that there are 4 gallons in a quart and that a volume of 1 liter is equal to that of 1.057 quarts. This problem can be worked by first converting gallons to quarts, then quarts to liters. The two unit conversion factors required are the following... 

Consider only the following information An object with a mass of 1 kg also has a mass of 2.2046 lb. A pound contains 16 ounces. A piece of chalk 2 inches long is also 5.08 cm long. There are 36 inches in 1 yard. A 1-liter volumetric flask contains 1.057 quarts. A cubic centimeter is the same volume as a milliliter. From this information, show how to calculate unit conversion factors to convert the following (a) from yards to meters ... 

A German recipe for making pastry dough calls for 1.2 L of milk. Your measuring cup only measures in cups. How many cups of milk should you use 4 cups (cp) = 1 quart (g). (Note Conversion factors like this, where 4 cp is defined as 1 g, are exact. Therefore, they do not limit the number of significant figures in the answer.)... 

For this calculation, you must make two conversions, one from liters to quarts and a second from quarts to cups ... 

If we are limited to the conversion factors in this text, this will require three conversion factors, one to convert from quarts to liters, one to convert from liters to milliliters and one to convert from milliliters to cubic centimeters.
