If you’ve ever picked up a full piggy bank, you know that coins are heavy.
However, just how heavy a coin is varies depending on the coin type.
Learning how much a certain weight in coins is in monetary value can help you estimate how much money you actually have saved in your piggy bank or jar.
How much does a dime weigh?
Dimes, which are the smallest United States coin, are exactly .705 inches or 17.91 millimeters in diameter. They have a thickness of about .05 inches or 1.35 millimeters. Each dime has a ridged edge. Dimes weigh exactly 2.268 grams or about .08 ounces.
This weight may fluctuate very slightly in older dimes due to either a buildup of dirt or wear to the coin. However, these fluctuations will be very small.
How many dimes are in 1 pound?
We know that one dime weighs .08 ounces. By dividing 1 ounce by .08, we can find that we would need 12 and a half dimes to make up exactly 1 ounce. It’s easier to work with whole numbers since we can’t physically split a dime in half, so we can multiply by two. This means that, in every two ounces, there are 25 dimes.
There are 16 ounces in 1 pound. We can divide 16 by 2 because we’re grouping dimes into 2-ounce increments.
Sixteen divided by two is eight, so we can multiply eight by 25 to find out how many dimes are in 16 ounces. The answer is 200, which tells us that there are 200 dimes in 1 pound.
A single dime is worth 10 cents. Multiplying 200, for the number of dimes, by 10 cents, or .10 gives us 20. This answer tells us that there is $20 worth of dimes in 1 pound.
How much money is in 10 pounds of dimes?
10 pounds of dimes equals $200. Here is how to perform the math.
Now that we know how many dimes, and how much those total dimes are worth, are in 1 pound, we can easily figure out how much money is in 10 pounds of dimes.
All we need to do is multiply the number of dimes in a pound, which is 200, by 10. The answer is 2,000, which tells us that there are 2,000 dimes in 10 pounds. If we multiply 2,000 by how much each dime is worth, which is 10 cents or .1, we get an answer of 200. This tells us that there is $200 worth of dimes in 10 pounds.
We can arrive at this answer even faster by cutting out a couple of steps.
Instead of multiplying by the total number of dimes in a pound, we can multiply by the monetary worth of dimes in a pound, which is $20.
Multiplying $20 by the number of pounds, which is 10, gives us the same answer of $200.
Now that we know how many dimes are in one pound, and what that pound of dimes is worth, it’s simple to figure out how much any number of pounds of dimes is worth.
All you need to do is multiply the number of pounds by $20.
For example, if you want to know how much money is in 7 pounds of dimes, multiply 7 by $20.
The answer is $140, which tells you that there’s this much money in 7 pounds of dimes.
How do I reverse the equation?
If you know how many dimes, and therefore how much money you have, but you don’t have a scale handy, you can easily reverse the equation from above.
Say you have $40 in dimes or 400 dimes. Simply divide $40 by $20. The answer is 2, which tells you that you have 2 pounds of dimes.
You could also divide 400, the number of dimes, by 200, the number of dimes in 1 pound, to get the same answer.
