Thank you so much for the help! I’m having to covert area to diameter - 1cm2 to diameter in meters for current density calcs and this saved my brain! Now I can use the formulas and get current densities Thanks 🙏🏼
The standard way of calculating the area of a circle is pi*r^2 where r (radius) is 1/2 of the diameter (d/2). If you square d/2 you get d^2/4. Substituting into the original area formula you get (pi*d^2)/4. pi/4 equals 0.7854. I also teach at a technical college (using Mr. Klette's Fluid Power textbook) but prefer students use the formula they were exposed to in middle school and high school to calculate the area of a circle (it is not hard taking 1/2 of the diameter to get the radius) instead of having to memorize another formula with a new constant.

Whatever happened to just Pi R2 ?
Nothing. it works but cylinder companies give the diameter not he radius. And this the formula that the IFPS uses.
@@KletteTech you could also use (pi*d^2)/4. All of the options work well enough for these purposes.
What for 78.54%
78.54% is the multiplier for when the diameter of the cylinder is known. It is a constant. Hope this helps.
