If it were in $1 bills, it would weigh three million grams or just less than 6,614 pounds.
You would need 600,000 $5 bills to make $3 million dollars, so, by multiplying 600,000 by 0.0353, the weight of one bill, we can find that the entire amount would weigh about 21,180 ounces.
We can simplify this and find the amount in pounds by dividing 21,180 by 16, which is how many ounces there are in a single pound. This gives us a total of 1,323.75 pounds.
It would take 300,000 $10 bills to make $3 million, and the entire amount would weigh about 661.875 pounds.
If we were using $50 bills, you would need 60,000 bills, which would weigh about 132.375 pounds.

How much space does $3 million dollars in $20 bills take up?
All U.S. dollar bills weigh the same, and they’re all the same size as well. A $20 bill is 2.61 inches wide and 6.14 inches long, and each bill is 0.0043 inches thick.
When they’re organized into large amounts of money, $20 bills are often stacked together in groups of $10,000, and a stack this size is about 2.15 inches tall, although it might sometimes be slightly taller due to any wrinkles in the bills.

You would need 300 stacks of this size to equal $3 million. If you arranged the stacks in groups of 20 stacks, with 20 stacks making up the bottom layer, and 20 more stacks on top, and so on until you’d organized all the stacks, the pile would be about 32.25 inches tall, or around 2.6875 feet.
Exactly how long or wide the entire pile of money would be would depend on how you’d arranged the individual stacks.
If the money was arranged in rows and columns of 10 stacks each, with the money’s longest side placed vertically, the pile would be 2.175 feet tall and about 61.4 feet wide.
