Unless otherwise specified, all fluid volume measurements in this manual are expressed in United States (U.S.) units-of-
measure. See below:
1 pint (U.S.) = 16 fluid ounces (U.S.)
1 quart (U.S.) = 2 pints (U.S.) = 32 fl. oz. (U.S.)
1 gallon (U.S.) = 4 quarts (U.S.) = 128 fl. oz. (U.S.)
Fluid volume measurements in this manual include the metric system equivalents. In the metric system, 1 liter (L) = 1,000
milliliters (mL). To convert between U.S. units-of-measure and metric units-of-measure, refer to the following:
fluid ounces (U.S.) x 29.574 = milliliters
pints (U.S.) x 0.473 = liters
quarts (U.S.) x 0.946 = liters
gallons (U.S.) x 3.785 = liters
milliliters x 0.0338 = fluid ounces (U.S.)
liters x 2.114 = pints (U.S.)
liters x 1.057 = quarts (U.S.)
liters x 0.264 = gallons (U.S.)
Fluid volume measurements in this manual do not include the British Imperial (Imp.) system equivalents. The following
conversions exist in the British Imperial system:
1 pint (Imp.) = 20 fluid ounces (Imp.)
1 quart (Imp.) = 2 pints (Imp.)
1 gallon (Imp.) = 4 quarts (Imp.)
Although the same unit-of-measure terminology as the U.S. system is used in the British Imperial (Imp.) system, the actual
volume of each British Imperial unit-of-measure differs from its U.S. counterpart. The U.S. fluid ounce is larger than the
British Imperial fluid ounce. However, the U.S. pint, quart, and gallon are smaller than the British Imperial pint, quart, and
gallon, respectively. To convert between U.S. units and British Imperial units, refer to the following:
fluid ounces (U.S.) x 1.042 = fluid ounces (Imp.)
pints (U.S.) x 0.833 = pints (Imp.)
quarts (U.S.) x 0.833 = quarts (Imp.)
gallons (U.S.) x 0.833 = gallons (Imp.)
fluid ounces (Imp.) x 0.960 = fluid ounces (U.S.)
pints (Imp.) x 1.201 = pints (U.S.)
quarts (Imp.) x 1.201 = quarts (U.S.)
gallons (Imp.) x 1.201 = gallons (U.S.)
