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.

Success!

I need the maximun of these two values.

These formulas represent the maximun reinforcement bar.

Re: How do I get the maximum of two values from different units?

That is only possible if

* f ' c*

is unitless.

Otherwise, as explained, it's nonsense.

Where is the worksheet...?

Success!

Re: How do I get the maximum of two values from different units?

Hi,

These are empirical equations the result of both is mm^2. Using empirical equations you must be careful to divide the inputs f'c, fy, b, d by the right units as used by the creator of the empirical equations..

Cheers
