Need Some Help With a Basic Coding Issue?

bmichaels556 · January 23, 2019

Well see... I'm having a bit of an issue and hoping someone could help me out?

I run a site that uses WordPress and wanted to add a foot-pounds energy calculator on it. Basically, I'd like for it to be pretty simple. Put in a projectile weight, put in a velocity (switchable between feet per second and meters per second), and have it spit out a Foot-Pounds Energy value.

The formula is: Energy = Weight times Velocity Squared divided by 450395 (fixed constant). Presumably this applies to weight in "grains", and velocity in feet per second. That seems easy enough to write with say, Python. But as to how I'd get that to work on a WordPress site, I wouldn't know.. Further, I wouldn't know how to be able to seamlessly switch between feet per second, and meters per second. I also don't think this could be done in pure HTML, could it? I took a class and was able to come up with a professional-looking site using only HTML, so I guess I "know enough to be dangerous", but that's about it. Plus, it's been a while..

Really hoping someone could help me with this? The best I could really offer is a followed link to a site of yours, or something like that. Not that it's worth much, but it's the best I can do at current time as I'm just trying to get this site off the ground.

Thanks so much for your help!

Totally forgot to reply, but I did end up using the plugin you recommended. After just about 15-20 mins of playing with it, it worked like a charm! Exactly what I needed. Much appreciated!
