Money Weight Calculator
Wonder how much a million dollars weighs, or how much cash is in a 10-pound bag of quarters? Enter a dollar amount and denomination to get the weight in grams, kilograms, ounces, and pounds. Flip to reverse mode and enter a weight to find out what it is worth. Every official U.S. coin and bill denomination is supported.
How much does U.S. currency weigh?
Every circulating Federal Reserve note - from a $1 bill to a $100 bill - weighs exactly 1.0 gram. That means denomination matters a lot when you are stacking up a large sum: a million dollars in $100 bills weighs only 10 kg (22 lb), while the same sum in $1 bills weighs a full metric ton (1,000 kg / 2,205 lb). Coins are heavier than notes relative to their face value and vary by denomination. A penny weighs 2.5 g, a nickel 5 g, a dime 2.268 g, a quarter 5.67 g, a half dollar 11.34 g, and the Sacagawea/Presidential dollar coin 8.1 g. Because dimes, quarters, and half dollars are all made from the same copper-nickel clad alloy, they share the same weight-per-dollar ratio of about 22.68 g per dollar of face value.
Forward mode: dollar amount to weight
Choose "Dollar amount to weight" from the mode selector. Enter the total face value in U.S. dollars, pick a denomination, and the calculator divides that amount by the face value of one piece to find the piece count, then multiplies by the official per-piece weight. For example, $50,000 in quarters: 50,000 ÷ 0.25 = 200,000 quarters, multiplied by 5.67 g = 1,134,000 g = 1,134 kg = about 2,500 lb. Results appear instantly in grams, kilograms, ounces, and pounds.
Reverse mode: weight to dollar amount
Flip the mode to "Weight to dollar amount," enter a weight in your preferred unit (grams, kilograms, ounces, or pounds), and select the denomination. The calculator converts your weight to grams, divides by the per-piece weight to get the piece count, then multiplies by face value. For example, 10 lb of quarters: 10 × 453.592 = 4,535.92 g, divided by 5.67 g = 799.99 quarters, times $0.25 = roughly $200. This is handy for coin jars, estate inventories, and curiosity questions.
Practical uses and fun facts
Money weight calculations come up in more contexts than you might expect. Armored car operators plan vehicle loads based on the total cash weight they carry. Banks order coin rolls by weight on shipping pallets. Coin collectors weigh lots to verify authenticity - a worn coin may be slightly lighter than spec. Some people weigh coin jars to estimate their value before rolling them. Pop-culture scenarios like "how much does a billion dollars weigh?" also have concrete answers: one billion dollars in $100 bills would weigh 10,000 kg, roughly the mass of two large African elephants. A stack of $1 bills worth a million dollars would be about 1 km tall and weigh a metric ton.

Frequently asked questions
How much does $1 million in $100 bills weigh?
Each $100 bill weighs 1 gram. One million dollars divided by $100 equals 10,000 bills. At 1 g each, that is exactly 10,000 g, or 10 kg (about 22.046 lb). It would fit inside a small briefcase.
How much does $1 million in quarters weigh?
Each quarter is worth $0.25 and weighs 5.67 g. One million dollars in quarters is 4,000,000 quarters. Multiplied by 5.67 g, that is 22,680,000 g, or 22,680 kg (about 50,000 lb / 25 U.S. tons). You would need a large flatbed truck to move it.
Do all U.S. bills weigh the same?
Yes. All circulating Federal Reserve notes - $1, $2, $5, $10, $20, $50, and $100 - weigh 1.0 gram each. They are all printed on the same type of paper (a cotton-linen blend) and cut to the same dimensions (6.14 in x 2.61 in / 156 mm x 66 mm), so denomination makes no difference to weight.
Why do dimes weigh less than pennies but are worth more?
Pennies are made mostly of zinc with a thin copper plating and weigh 2.5 g. Dimes are much smaller coins made from copper-nickel clad and weigh 2.268 g. The coin's weight reflects its size and composition, not its face value. Historically, silver dimes were smaller and lighter than silver pennies because silver is denser and more valuable per ounce, so less metal was needed. The modern clad versions kept those legacy dimensions.
Can I use this to estimate the value of a coin jar?
Yes, with reasonable accuracy. Weigh your jar, subtract the jar's tare weight, then enter the net weight and select the predominant coin denomination. For a mixed jar, quarters are the most common large-value coin and give a rough estimate. For a more precise count, sort by denomination, weigh each group separately, and add up the results.
How much does a roll of quarters weigh?
A standard U.S. quarter roll contains 40 coins worth $10.00. At 5.67 g each, a full roll weighs 40 x 5.67 = 226.8 g (about 8 oz / 0.5 lb). A box of 50 rolls (2,000 quarters, $500 face value) weighs 11,340 g, or 11.34 kg (25 lb).
