If Time since first Apple ][ computer launched (47 y) was a standard unit ...

Time since the end of the Pleistocene geologic epoch (11,700 y)...more would be 250 x Time since first Apple ][ computer launched

Time since the birth of Euclid (2,384 y)...more would be 50 x Time since first Apple ][ computer launched

Time since the birth of Alexander the Great (2,379 y)...more would be 50 x Time since first Apple ][ computer launched

Time since the peak of Roman Empire (1,900 y)...more would be 40 x Time since first Apple ][ computer launched

Lifespan of Galapagos giant tortoise (190 y)...more would be 4 x Time since first Apple ][ computer launched

Time since the publication of Einstein's theory of Special Relativity (119 y)...more would be 2.5 x Time since first Apple ][ computer launched

Time since the birth of computer scientist Grace Hopper (118 y)...more would be 2.5 x Time since first Apple ][ computer launched

Time since first Model T Ford launched (116 y)...more would be 2.5 x Time since first Apple ][ computer launched

Period of Jupiter's orbit (11.86 y)...more would be 1/4 of Time since first Apple ][ computer launched

Period of Mars's orbit (1.88 y)...more would be 1/25 of Time since first Apple ][ computer launched
