Gugor is the largest unit of counting. It represents the number 1 followed by 100 zeros, that is, the power of 100, that is, 100 zeros followed by 1. This value is very large, far exceeding the numerical range that we can imagine in our daily life. The word Gugor was put forward by American mathematician Edward Casner in 1930s, and his nephew Milton Silota gave it a name. The word Google is also used to describe the origin of Google's name.
