If Age of the Earth (4.54 billion y) was a standard unit ...

Time since the start of the formation of the Solar System (4.6 billion y)...more would be about as big as Age of the Earth
Galactic Year (period of rotation of the Milky Way galaxy) (225 million y)...more would be 1/20 of Age of the Earth
Time since the end of the Paleogene geologic period (23 million y)...more would be 1/200 of Age of the Earth
