Apr 2, 2022 · $\begingroup$ PetaFLOP/s-days most likely means 1 day of petaFLOPS, i.e. $8.64 \times 10^{19}$ floating point operations. $\endgroup$ – Zhen Lin Commented Apr 2, 2022 at 2:49

I would like to be able to plug in different values into the formula to change the number of petaFLOPS e.g. $200, 1000$ and get different outputs. 2) If I get a result from the above formula, e.g. $2^{85}$ operations per second, I need a second formula to determine how long it would take in seconds to do $2^x$ operations e.g. $2^{100}$ operations.
