Have you ever wondered how much a certain amount of money weighed? For instance, how much money would you have if you had a pound in $100 bills? If you have, you’ve come to the right place.

**A $100 bill weighs 1 gram. There are 453.592 grams in a pound, so a pound in $100 bills would equal at least $45,300.**

There are other things you need to take into account when measuring money by weight. Below, I’ll cover those things, as well as describe how you can calculate how much money you would have if you measured paper money by weight.

**Calculating $100 by Weight**

As described above, a single $100 bill weighs 1 gram. Because 1 pound is the same as 453.592 grams, you can calculate how many bills you would need to total 1 pound by multiplying how many grams there are in a pound by $100.

I’ll illustrate briefly down below:

- 1 × pound = 453.592 grams
- 1 × $100 = 1 gram
- 1 × 453 $100 = 1 × 453 grams
- 453 × $100 = 453 grams = 1 pound
- $45,300 = 453 grams = 1 pound

Knowing this figure, you can easily calculate how much money you would have in $100 by any weight.

Here’s a quick table that will tell you how rich you would be if you had a certain weight of $100 bills.

Weight (pounds) | Weight (grams, rounded down) | Total Value |

1 pound | 453 | $45,303 |

1.5 pounds | 680 | $68,000 |

5 pounds | 2,267 | $226,700 |

15 pounds | 6,803 | $680,300 |

22.04 pounds | 10,000 | $1,000,000 |

125 pounds | 56,699 | $5,669,900 |

Although you could round up the total grams per pound figure, you might want to take a more conservative approach by rounding down instead, especially when calculating money by weight.

Also, because you cannot tear a $100 bill in half and call it a whole $100, it makes more sense to round down instead of up.

**What Factors Affect Banknote Weight**

A freshly printed US bill will measure precisely 1 gram. However, after the bill has left the printing press, it will begin to gradually lose fractions of a gram of weight over time.

Here are the factors that will affect a dollar bill’s weight:

- Age—the longer the $100 bill has been in distribution, the more fibers it will lose, thus, reducing its weight.
- Year of print—today, US paper money measures 6.14 × 2.61 inches. Prior to 1929, they measured 7.375 × 3.125 inches, which is about 30% larger than current dollar bills. Their larger size would also make them heavier.
- Contamination—it was found that over 90% of US bills were contaminated with trace amounts of illegal narcotics. While they would only add a fraction of a gram to each bill, the additional weight could add up when measuring millions of dollar bills.

**Do All Bills Weight the Same?**

Yes, they do.

Regardless of the denomination, US paper money is designed to weigh exactly the same as each other. That means you would find the same number of bills in a pound of $1 as you would a pound of $100.

So, if you collected a pound of every denomination, you would have:

Weight | Denomination | Total |

1 pound | $1 | $453 |

$2 | $906 | |

$5 | $2,265 | |

$10 | $4,530 | |

$20 | $9,060 | |

$50 | $22,650 | |

$100 | $45,300 |
