When measured in U.S. $1 bills, a million dollars weigh 2,202.6 pounds. The denomination of bills has a big effect on the weight.
A million dollars in $1 bills is also equal to about 1 metric ton but weighs about 1.1 tons by U.S. measure. Each time the denomination of the bills is increased, the weight of a million dollars decreases. When weighed in $100 bills, a million dollars weighs approximately 22 pounds.
The same is true when measuring the amount of space a million dollars takes up. A bill of U.S. currency is 0.0043 inches thick. A stack of a million dollars in $1 bills measures about 358 feet in height. In contrast, a stack of $1 million in $20 bills is about 18 feet tall.
U.S. paper currency weighs 1 gram regardless of the denomination. A person could easily fit $1 million in cash into a rolling suitcase for travel, though electronic bank transfers are generally used instead of cash for transactions involving large sums of money.
