How Much Does a Million Dollars Weigh? (Revisited)

Awhile back, I investigated whether or not a million dollars really is a ton of money. As it turns out, the answer depends on whether or not you use the metric system. A million dollars in one dollar bills weighs in at a metric ton, or about 1.1 US tons. So then I got to thinking…

What if you had a million dollars in pennies? How much would that weigh? To get to the bottom of this mystery, I once again weighed some money. This time it was ten pennies, which weighed in at 26.15 grams. Assuming that this is representative of the pennies that are out there in circulation, we can now do a bit of math…

Let’s see… 2.615 grams per penny, 100 pennies in a dollar. That makes… Hrrrmmm… Carry the one… 261, 500, 000 grams or 261, 500 kg. This corresponds to 261.5 metrics tons. Given that a metric ton is roughly 2200 pounds, we’re talking about 575, 300 pounds, or just a shade under 288 US tons.

But wait! A penny really isn’t worth a penny anymore! What’s that, you say? A penny’s not worth a penny? Well, with recent reports that pennies actually cost 1.5 cents to produce, we need to adjust the numbers a bit. At a penny and a half per penny, if you were looking to mint pennies and you had a million bucks to spend, you be able to produce 66, 666, 667 pennies. So how much would that weigh? A hefty 383, 533 pounds, or just a touch below 192 US tons.

What’s the point of all this? I’m really not sure, but it struck me as an entertaining exercise, and the recent news about how much a penny really costs just heightened my curiosity. Oh, and in case you’re curious, the US Mint estimates that there are as many as 140 billion pennies in circulation today — that’s 1.4 billion dollars.

So there you have it… Your math lesson for the day.

    It is almost wothless to know but god is it mentally stimulating to think about. Thank you for getting an average weight being that money loses mass over time. Anymore articles like this?

  4. Bill: Re-read the post. I was calculating the value for million dollars in pennies. That would be 1,000,000 x 100 pennies. Your estimate was for 1M pennies, which is just $10k. My math is correct, as is yours, but you were answering a different question.

    Your math is wrong, one million pennies is only 2.5 tons. Not 288 tons. The U.S. penny has a mass of 2.5 gram; multiplied by a million gives you 2500 kg. or 2.5 tonnes.

    I’d like to see us all do without pennies. everything would have to be rounded up to a nickel. save them pennies up. By the time I cash them in I get about $80. Don’t be dumb matt.

    I sometimes wonder how many of those pennies “in circulation” really are, given the incredibly low value density of pennies in recent years. I probably have $20 or more worth of pennies scattered around my apartment. When I get pennies in change, I usually leave them on the counter. Turning them into spendable money takes so long that it’s no longer worth it to me…and I know I’m far from the only one who feels this way.
