Quarters to Dollars Converter
Count quarters like a bank teller. Enter how many quarters you have to get the dollar value, the number of standard $10 rolls they fill, and the weight in grams and pounds.
Example: with Number of quarters 100 → Dollar value: $25.00.

Face value: 4 quarters = $1. Weight uses the US Mint spec of 5.670 g per quarter; a standard bank roll holds 40 quarters ($10).
The 25-cent math
A quarter is 25 cents, so 4 make a dollar — multiply your coin count by $0.25 or divide by 4. A coffee can holding 137 quarters is $34.25; a full laundry-day handful of 16 covers $4.00 of machines.
Banks roll quarters 40 to a roll, which is $10 of face value — the highest-value standard roll. The converter shows full rolls plus loose coins so you know what's deposit-ready.
Weigh it instead of counting it
Every modern US quarter weighs 5.670 grams by Mint specification. That gives quarters the same handy ratio as dimes: $20 in quarters (80 coins) weighs 453.6 grams — one pound within a gram. Weigh your stash in pounds, multiply by 20, and you have dollars; or divide total grams by 5.67 to count coins.
How it’s calculated
Dollars = quarters × $0.25 (4 quarters per dollar). Rolls = quarters ÷ 40, the standard bank roll ($10 face value). Weight = quarters × 5.670 g, the US Mint specification for the Washington quarter, converted at 453.59237 g per pound (exact NIST factor).
Weight math assumes clad quarters minted 1965 or later; 90%-silver quarters from 1964 and earlier weigh 6.25 g and are worth far more than 25 cents.
Quarters, rolls, and weight at common dollar amounts
| Dollar amount | Quarters | Rolls of 40 | Weight |
|---|---|---|---|
| $1 | 4 | a tenth of a roll | 22.7 g (0.05 lb) |
| $5 | 20 | half a roll | 113.4 g (0.25 lb) |
| $10 | 40 | 1 roll | 226.8 g (0.50 lb) |
| $20 | 80 | 2 rolls | 453.6 g (1.00 lb) |
| $100 | 400 | 10 rolls | 2.27 kg (5.00 lb) |
Computed from US Mint coin specifications: 5.670 g per quarter, 40 quarters per standard bank roll.
Common mistakes
- Assuming quarter rolls hold 50 coins — they hold 40 ($10); penny and dime rolls are the 50-coin ones.
- Letting nickels mix in: a nickel (5.000 g) weighs nearly what a quarter (5.670 g) does but is worth a fifth as much, so scale counts drift badly.
- Entering dollars instead of coins: 100 means 100 quarters ($25), not $100.
- Spending pre-1965 silver quarters at face value — their silver content alone is worth many times 25 cents.
Frequently asked questions
How many quarters make a dollar?
4 — each quarter is 25 cents. So $5 is 20 quarters, $10 is 40, and $20 is 80.
How much is a roll of quarters?
$10. A standard bank roll holds 40 quarters, making it the most valuable common coin roll. Two rolls is a typical laundry-week supply.
What is the conversion formula?
Dollars = number of quarters × 0.25, or equivalently quarters ÷ 4. Going the other way, quarters = dollars × 4.
How many quarters do I need for laundry?
Multiply the machine price by 4 per dollar: a $2.50 wash takes 10 quarters, and wash plus dry at $4.00 total takes 16. A $10 roll typically covers two to three full loads.
How much do quarters weigh?
5.670 g each, so $20 in quarters weighs almost exactly one pound (453.6 g) and $100 weighs about 5 pounds. Dimes share the same $20-per-pound ratio.
