A quadrillion is equal to 1015 in America, or 1024 in France and Germany.[1]
Quadrillion Dollars

1 quadrillion dollars in 5 piles of 100 dollar bills in comparison to the Empire State Building.

In the long scale, 1015 is called billiard (not to be confused with a game), which is commonly used in France and Germany.

This number is also called pentillion in Russ Rowlett's Greek-based naming system.[2]

Aarex Tiaokhiao gave the name petillion[3] and Sbiis Saibian gave the names small fry, guppycrumb, and minnowspeck,[4] referring to the value of this number.

Aarex Tiaokhiao also calls this number qndoocol or 15-noogol.[5]
