Orders of magnitude (time).

When you choose an order of magnitude you must also choose it’s inverse.

For example if you choose femtoseconds (fs) it’s inverse is petaseconds (Ps):

t = 1 second

T^1 = 1015 fs

T^2 = (1 × 1015) / (1 / 1015) = 1030 fs²

A = 1 × 1015 = 1015 femtoseconds (fs)

B = 1 / 1015 = 10−15 petaseconds (Ps)
