To convert liters to fluid ounces: liters x 33.81 = fluid ounces
Liters IS volume - there is nothing to convert.
atmospheres
To convert cubic meters to liters, you multiply by 1000.
mmHg x 0.001316 = atmospheres749 mmHg x 0.001316 = about 0.9855 atm
Multiply psi x 0.07 to get atmospheres.
First convert quart into liters (multiply by 1.1365), then convert liters into milliters (multiply by 568.26)
There are approximately 0.2 atmospheres in 150 mm Hg. To convert from mm Hg to atmospheres, you can use the conversion factor that 1 atm is equal to 760 mm Hg.
To convert millimeters of mercury (mmHg) to atmospheres (atm), divide by 760. So, 734 mmHg is equivalent to approximately 0.965 atm.
A hectoliter is equal to 100 liters so 42.9 hectoliters would convert to 4290 liters.
To convert hectoliters (hl) to liters, you multiply by 100 because there are 100 liters in a hectoliter. Therefore, 0.9 hl is equal to 90 liters.
Convert everything to the same unit, then add. (Either divide milliliters by 1000 to convert to liters, or multiply liters by 1000, to convert to milliliters.)
