I don't know what other people think, but obviously you're not an electronics guru (neither am I!). I get pretty careful when it comes to things I'm plugging into the mains. If you were just measuring power consumption of a single chip, it would be different. So I'd be tempted to buy a plug in power meter (something like this ) and then figure out where it puts it's output into whatever drives its LCD display. Then read that into the arduino.
However, in the future, something like this may be the ticket:

Also check out this if you want to try and make something yourself.
check your motherboard manual, usually the b slots (2 and 4) are preferred for dual kits, although this shouldn't be the issue.
best way to check powerdraw is to get a meter like this one:

Just a standard home AC power meter.

Have you ever plugged in a watt meter to see what your PC consumes over say a week? Something like this: https://www.amazon.co.uk/Energenie-429-856UK-Power-Meter/dp/B003ELLGDC.
Kettles use a lot of electricity, but for a very short amount of time (unless you fill the kettle right up every time like an insane person).
At my day rate electricity of about £0.21 per kWh, it would cost about £0.63 if I left the kettle boiling constantly for an hour. It generally takes about 2 minutes to boil the kettle with enough water for two cups (minimum fill), so the cost of the kettle works out at between £0.01 and £0.02 per cup depending on whether I make one for just myself or use the extra water to make someone else a brew.
It's misleading to only look at how much power something consumes without paying attention to how long it's actually on for.
If you want more insight into how much electricity a specific appliance actually uses, these are alright. Set the time, set your electricity rate (it supports differential tarrifs [economy 7, 10, etc] too), then plug it in for a couple of hours/days/whatever and it'll tell you how much power it's used, how much it's cost so far.
It also shows some other stuff that most people probably won't find useful like how much current the appliance is drawing, voltage, frequency, and power factor.
What every one has said about profitability is correct - but personally I've only ever mined bitcoins for a bit of fun. Its a good learning exercise - and if your interested in Bitcoin its a good way to learn more about it.
Bottom line is with your setup, its never going to be profitable - so I wouldn't worry too much about the maths - it will only depress you!
To answer your Q's though -
