And for good reasons! Essentially you're comparing apples to oranges, or pears, or berries... In general it's nonsensical, certainly from a physical standpoint.

Bear in mind that if you express t in mm, and h in kg, then 't' will provide the larger value.

I need the maximun of these two values.

These formulas represent the maximun reinforcement bar.

That is only possible if 

 f ' c

is unitless.

Otherwise, as explained, it's nonsense.

Where is the worksheet...?
