It means the weight of 500 sheets of the basis paper used to make the finished product. For instance, standard 8-1/2" X 11" paper is actually cut from a 17" X 22" basis, which produces 4 sheets when cut. So, 500 sheets of 17" X 22" paper that weighs 20 pounds would be 20 lb paper. Once it is cut and packaged for sale, 500 sheets no longer weighs 20 pounds, so the number becomes a guide for you to judge the relative thickness of different papers.

Mathematically they have equal value, assuming that a 50 dollar bill has the same mass (weight) as a 20 dollar bill. Think of it like this: let's say that there is a quantity (N) bills in 1 pound (lb).The 20 lb bag has 20*N bills; each bill worth 50, so 20*N*50 = 1000*N.50 lb bag has 50*N bills; each bill worth 20, so 50*N*20 = 1000*N.On a practical note, each one has an advantage, which may or may not be of different 'worth' to the user. The 20 pound bag will definitely be easier to carry around than the 50 pound bag, but then $20 bills should be easier to spend than $50 bills.
60 minutes = 1 hour → 20 minutes/lb x 20 lb = 400 minutes = 400 ÷ 60 minutes = 6 hours 40 minutes. [Cooking time would be 7 hours, as an extra 20 mins is [usually] added.]

4.7 mil paper is thicker than 20 lb paper. Mil is a unit of measurement used to describe the thickness of paper, with 1 mil equal to 0.001 inches. Therefore, 4.7 mil paper would be approximately 4.7 times thicker than 20 lb paper.
There are 500 sheets in a 20-lb. ream of paper.
20 lb. bond paper isn't 20 pounds of bond paper, but rather the basis weight, which measures the density of the paper based on how heavy 500 sheets of that paper is. A single sheet of this type of paper is, on average, 4/1000 of an inch thick.
10 lbs. The 20 lb. weight refers to the weight of a ream of C size paper, which is 4 times the size of letter paper, or twice the size you ask about.
A case of 20 lb letter size paper typically weighs around 50 pounds, as there are typically 10 reams of 500 sheets each in a case.
The term "20 lb." refers to the weight of propane that the tank can hold when filled to its maximum capacity. The tank itself, when empty, may weigh around 18-20 pounds, hence the designation as a 20 lb. propane tank.
Heavy weight paper is actually thicker paper. Paper comes in lb. If you read your printer manual it will tell you what weight paper you can use. For instance it may say 24 lb or 28 lb etc. the bigger the lb the heavier the paper (or thicker the paper).
20 reams or 10,000 sheets of 20 lb paper would weigh approximately 100 pounds.

The weight of a ream of paper depends on the kind of paper. A ream is 500 sheets. The weight for 500 sheets of 24 lb., 11 inch x 17 inch book paper would be 4.72 pounds. A ream of 20 lb. 8.5 inch by 11 inch letter-size paper weights 5.00 pounds.
The weight of 6 sheets of regular copy paper (20 lb, 75 gsm) is approximately 5.1 ounces or 145 grams.
Percent means "out of 100" → 20% of £29 = 20/100 × £29 = £5.80 or 20% of 29 lb = 20/100 × 29 lb = 5.8 lb = 5 lb 12.8 oz
