Whether you’re a coin collector, bank teller, business owner, or simply someone rolling up change at home, knowing the total weight of your coins can be incredibly useful. With different denominations having unique weights, calculating the total can be time-consuming and error-prone if done manually.
That’s why we created the Coin Weight Calculator—an easy-to-use, accurate online tool that instantly provides the total weight of your coins in grams. All you need to do is input how many of each U.S. coin you have, and the calculator does the math for you.
🧾 What is the Coin Weight Calculator?
The Coin Weight Calculator is a practical tool that calculates the total weight of a combination of U.S. coins. By inputting the number of pennies, nickels, dimes, quarters, half dollars, and dollar coins you have, the calculator multiplies each quantity by the coin’s official weight and sums it up for a final total in grams.
This tool is perfect for:
- Estimating shipping weight for coins
- Helping banks and businesses manage coin deposits
- Assisting collectors with coin inventory
- Determining whether you’re carrying too much loose change
🧮 Coin Weight Formula
The formula used in this tool is based on the official weight of U.S. coins, as follows:
- Penny (1 cent): 2.5 grams
- Nickel (5 cents): 5 grams
- Dime (10 cents): 2.268 grams
- Quarter (25 cents): 5.670 grams
- Half Dollar (50 cents): 11.340 grams
- Dollar Coin (e.g., Sacagawea, Presidential): 8.1 grams (Note: Multiplied by 10 in this calculator for 81 grams)
Total Weight =
(number of pennies × 2.5) +
(number of nickels × 5) +
(number of dimes × 2.268) +
(number of quarters × 5.670) +
(number of half dollars × 11.340) +
(number of dollars × 81)

📊 Example Calculation
Let’s say you have:
- 100 pennies
- 50 nickels
- 40 dimes
- 25 quarters
- 10 half dollars
- 5 dollar coins
Using the formula:
- Pennies: 100 × 2.5 = 250 grams
- Nickels: 50 × 5 = 250 grams
- Dimes: 40 × 2.268 = 90.72 grams
- Quarters: 25 × 5.670 = 141.75 grams
- Half Dollars: 10 × 11.340 = 113.40 grams
- Dollar Coins: 5 × 81 = 405 grams
Total Weight = 250 + 250 + 90.72 + 141.75 + 113.40 + 405 = 1,250.87 grams
So, your coins weigh approximately 1,250.87 grams, or 1.25 kilograms.

🧠 Helpful Tips
- Always use whole numbers for input.
- If you don’t have a specific coin type, just enter 0.
- The calculator uses grams as the unit—common for most weighing purposes.
- To convert grams to pounds, divide the total by 453.592.
Example:
If your total weight is 1,250 grams, then:
1,250 ÷ 453.592 ≈ 2.76 pounds
🔁 Difference Between Coin Weight and Face Value
- Face Value is the total monetary value of the coins (e.g., 100 pennies = $1).
- Coin Weight is the physical weight of the coins in grams.
They are not proportional—for example, a nickel weighs more than a dime, even though it’s worth less.
