Coin Weight Calculator

What is the Coin Weight Calculator?

The Coin Weight Calculator helps you determine the total weight of a collection of U.S. coins. This is useful for coin collectors, cashiers, bank tellers, or anyone who needs to weigh large amounts of change for inventory, transport, or mailing purposes.

Formula

The weight of a collection of U.S. coins is calculated using:

[\text{Weight (grams)} = (P \times 2.5) + (N \times 5) + (D \times 2.268) + (Q \times 5.670) + (HD \times 11.340) + (Do \times 8.1)]

Where:

• P = Number of pennies (2.5 grams each)
• N = Number of nickels (5 grams each)
• D = Number of dimes (2.268 grams each)
• Q = Number of quarters (5.670 grams each)
• HD = Number of half dollars (11.340 grams each)
• Do = Number of dollar coins (8.1 grams each)

To convert to pounds: Weight (lbs) = Weight (grams) / 454

Calculation Example

Given:

• 15 pennies
• 12 nickels
• 7 dimes
• 8 quarters
• 3 half dollars
• 2 dollar coins

Calculation:

[\text{Weight} = (15 \times 2.5) + (12 \times 5) + (7 \times 2.268) + (8 \times 5.670) + (3 \times 11.340) + (2 \times 8.1)]

Breaking it down:

• Pennies: 15 × 2.5 = 37.5 grams
• Nickels: 12 × 5 = 60 grams
• Dimes: 7 × 2.268 = 15.876 grams
• Quarters: 8 × 5.670 = 45.36 grams
• Half Dollars: 3 × 11.340 = 34.02 grams
• Dollar Coins: 2 × 8.1 = 16.2 grams

Total: 208.956 grams (approximately 0.46 pounds)
