The Coin Weight Calculator helps determine the total weight of a collection of U.S. coins based on the number of each denomination. This tool is useful for estimating bulk coin weight for shipping, banking, and storage purposes.
Formula
The total coin weight is calculated using the formula:
W = P × 2.5 + N × 5 + d × 2.268 + Q × 5.670 + HD × 11.340 + D × 81
Where:
- W = Total weight in grams
- P = Number of Pennies (2.5g each)
- N = Number of Nickels (5g each)
- d = Number of Dimes (2.268g each)
- Q = Number of Quarters (5.670g each)
- HD = Number of Half Dollars (11.340g each)
- D = Number of Dollar Coins (81g each)
How to Use
- Enter the quantity of each coin denomination.
- Click Calculate to compute the total weight.
- The result will be displayed in grams.
Example
If you have:
- 10 Pennies
- 5 Nickels
- 8 Dimes
- 12 Quarters
- 2 Half Dollars
- 3 Dollar Coins
Using the formula:
W = (10 × 2.5) + (5 × 5) + (8 × 2.268) + (12 × 5.670) + (2 × 11.340) + (3 × 81)
W = 25 + 25 + 18.144 + 68.04 + 22.68 + 243
W = 401.864 grams
