Money Weight Calculator

The Money Weight Calculator lets you find out how much any US dollar amount weighs across different bill denominations and coin types. Whether you are curious about the weight of $1 million in $100 bills, planning a large cash transaction, or wondering how heavy your piggy bank savings are, this tool gives you instant answers in grams, kilograms, pounds, and ounces.

All US Federal Reserve notes — regardless of denomination — weigh exactly 1 gram. That means a $1 bill, a $20 bill, and a $100 bill all weigh the same: 1 gram. Coins, however, vary significantly. A penny weighs 2.5 grams, a nickel 5 grams, a dime 2.268 grams, a quarter 5.670 grams, a half dollar 11.340 grams, and the dollar coin weighs 8.1 grams. The calculator works by dividing your total amount by the denomination's dollar value to find the number of bills or coins needed, then multiplying by the unit weight.

The tool also works in reverse: switch to Weight to Amount mode, enter a weight in grams, and it will tell you how much money that weight represents for your chosen denomination. Interactive comparison charts let you visualize how weight and unit count vary across all 13 denomination types at once — from pennies to $100 bills. For example, $10,000 in $100 bills weighs just 100 grams (about 0.22 pounds), while the same amount in pennies would weigh 2,500 kilograms (about 5,511 pounds).

This calculator is perfect for collectors, cash handlers, event planners, educators teaching the physical properties of currency, and anyone curious about the tangible weight of money. All results are based on official US Mint and Federal Reserve specifications.
