How much would 20000000 worth of pennies weigh?
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.
