The question isn't completely clear - is it referring to British pennies, or US cents which are called pennies in general conversation? Does "20000000 worth" mean 20,000,000 coins or coins worth $20,000,000.00 / £20,000,000.00?
In any case the arithmetic works the same way. You just have to plug in the different weights of British and American pennies.
Assuming you're referring to a pile of US cents worth $20,000,000.00, there are 100 cents in $1 so 20 million dollars of cents would need 100 x 20 million coins, i.e. 2 billion.
US cents made since 1982 weigh 2.5 gm, so 2 billion cents would weigh 2.5 x 2 billion gm, or 5 billion gm.
There are 1000 gm in a kilogram so dividing 5 billion by 1000 converts that to 5 million kilos.
Similarly there are 1000 kilos in a tonne so 5 million kg = 5,000 tonnes.
Grams are not a measure for weight so the question is like asking how many kilometres would a dollar worth of pennies weigh!
A box of pennies that contains $25 worth of pennies would have 2,500 pennies, as each penny is worth $0.01. Since a penny weighs 2.5 grams, the total weight of the pennies would be approximately 6,250 grams, or about 13.8 pounds.
1 billion pennies would weigh 5,511,556.55 pounds. The weight of a penny is 2.5 grams
One pound is equal to 100 pennies. Since a penny is worth one cent, it takes 100 pennies (or one dollar) to equal a pound in weight. Therefore, if you're referring to the weight of pennies, 100 pennies would weigh approximately 1 pound.
7,142 pennies weighs about 39.4 (39.3635369)pounds.

One penny weighs 2.5 grams, so 3,500 pennies weigh 8,750 grams.
Pennies after 1982 weigh ~2.5 grams.There are 453.59237 grams in a pound.90 pounds * 453.59237 = 40823.3133 grams in 90 pounds.40823.3133 / 2.5 grams = 16329.32532 pennies in 90 pounds.16329.32532 pennies / 100 pennies in a dollar = $163.29So 90 pounds worth of pennies would be $163.29.
The weight of a single penny is approximately 2.5 grams, or 0.00551156 pounds. Therefore, 8 pounds of pennies would be equivalent to approximately 1450 pennies (8 / 0.00551156). In terms of monetary value, each penny is worth $0.01, so 1450 pennies would be equal to $14.50.
38000 copper pennies would weigh approximately 94.7 kilograms or 209 pounds.
A single penny (after 1982) weighs 2.5 grams, so 10,000,000 pennies would weigh 25,000,000 grams, 55,115.5655 pounds, or 27.5577827 short tons.
Pennies weigh about 2.5 grams each. There are roughly 181 pennies in a pound and 2,381 pennies in a gallon. So, a 1 gallon water jug filled with pennies would weigh approximately 9.5 pounds.
About 5 pounds and 8 ounces. Basically only somewhere between 5 or 6 pounds.
1 billion pennies would weigh 5,511,556.55 pounds. The weight of a penny is 2.5 grams
7,142 pennies weighs about 39.4 (39.3635369)pounds.
Modern zinc (1982-present) pennies weigh 2.5 grams each, and copper pennies (pre-1982) weigh 3.11 grams each. 50 new ones weigh 125 grams and 50 old ones weigh 155.5 grams. A mix of the two weighs somewhere in the middle.50 US pennies would weigh about .338 pounds.
