Convert Amps to Watts

[bughatti]

So since I am on linux now with my rigs and I also installed 220 in my house, I can no longer use my killawatt meter to gauge each rig on kwh usage.  I could buy 1 for 220v but it would require me to shut all my rigs down and re wire a few things. 

In the meantime I bought a clamp meter to see what amps I am using.  Since I have 2 hot legs and a ground on my 30A plug, I clamped each hot wire and added them.  I found this calculator online http://www.plug.at/pl/calculator.htm to determine how many watts I am up to.

My question is does anyone have a better site to use or a better method?  Linux has nothing like gpu-z or hwinfo64 for me to gauge each rig.

amps x volts =watts

no calculator needed

220volts at 10 amps would be 2200watts

With this meter you can continuously monitoring your amp usage , easy to install .. you dont need to connect the red/orange/yellow wires , those wires is just for backlight ...
then basic math : amps x volts =watts

Here's the route I went:
https://www.amazon.com/Elgato-Energy-HomeKit-Technology-Bluetooth/dp/B01M3PK5WH/ref=sr_1_fkmr1_1?ie=UTF8&qid=1489902199&sr=8-1-fkmr1&keywords=eve+energy+220v

So on my iPhone I can see how much each rig is using, how much in $ it has cost since the last time it was reset, can remotely turn them on and off, etc.

I can do all of this from anywhere in the world.

Supports 240v.
