Might be because lb is an abbreviation for pound?

One pound of propane will produce 21,622 BTU's. 20 pounds of propane will produce 432,440 BTU's. A heater that produces 80,000 BTU's per hour will produce heat for almost 5 1/2 hours.
Theres about 430,000 btu's in a 20 lb propane tank. it your grill is 43,000 btu's it would last 20 uses.
Depends on the mass and what you are weighing. Gallons is a measure of 'capacity'. In a five gallon container you could put five gallons of water, which would weigh about 50lbs, but five gallons of petrol, which is lighter than water, would weigh less.
20 LBS OF PROPANE WILL PRODUCE APPROX. 36,000 BTU @ 0 DEGRESS, 51,000 @ 20 DEGREES.
20 lbs
of course 1 propane tank will allow you to cook for hours and a turkey takes less than 30 min.
A 20 pound propane tank holds 4.1 gallons of LP which equates to about 0.016 cubic meters. If your heater burns 3 m3 per hour the tank will last about 19 seconds. If you meant .0003 then it will last 51.73 hours.
20# tanks holds up to 20 #s of propane. The tank weight itself is designated as TW on the tank collar (usually 17-19 lbs)

The Letters "WC" on a propane tank stand for "Water Capacity", and are followed by a number which would identify the tanks Water Capacity typically measured in lbs. Water weighs approximately 8.3lbs per gallon Propane weighs approximately 4.24lbs per gallon
The MH80CV, part of the Mr. Heater Contractor Series, is a 30,000-80,000 BTU Propane Convection heater. The MH80CV provides reliable heat for areas up to 1900 sq. feet. It will operate for up to 14 hours on a 20-lb propane tank. The MH80CV features a standing pilot, piezo push-button ignition, and 'insta-lock' chamber for easy assembly. The MH80CV comes ready to use with the included hose and regulator. It operates on a 20-lb or larger propane tank (not included).There are a couple of other factors that may effect the time a 20 pound cylinder will last on a heater. Propane is stored in liquid form in the tank and must evaporate to be used in most heaters. The colder the temperature the propane tank is stored at the lower the pressure is in the tank. As the liquid propane evaporates it cools down the liquid propane still in the tank. As a result at minus -20 you might have a half full twenty pound tank and not have enough pressure to run the heater.
Propane freezes at -40 degrees C (which also happens to be -40 degrees Fahrenheit).
About 4.1 gallonsPropane is a gas at standard temperature and pressure. A 20-pound tank holds about 4.1 gallons of liquid propane. It's a liquid in the tank because it's under great pressure. 4.2 lb per US gallon5.1 lb per Imperial gallon

a typical steel "30 pound" liquid propane tank weighs about 25-28 pounds empty. propane tank markings (on collar) propane weighs about 4.125 pounds per gallon and a "30 pound tank" will hold about 7.5 gallons so a full tank will weigh about 55 pounds or so. Typical recertification stamp: MM XXX YY E MM -> 2 digit recertification month XXX ->3 character Re-qualifier's registration number YY -> 2 digit recertification year E ->States the cylinder has been externally examined WC -> Water capacity of the cylinder. TW -> Tare weight of the cylinder (what the tank weighs empty) ICC, DOT, BTE, CTC or TC -> Specification number eg. TC4BA240 10 89 -> Date of manufacture (October. 1989)
