Can somebody help me with how to make this conversion in general?
For example: Wind is coming from the east @ 13 knots. What does that mean in mph?

1KT = 1.15MPH

Technically, a knot is a measure of distance, called a nautical mile, rather than speed. When you hear wind or speed as x knots, it actually refers to knots per hour.
The mile is known as a statute mile.
e.g., if you're flying at a speed of 100 knots, it's really 100 knots per hour, or about 115 miles per hour.

Technically speaking a knot is a measure of speed (in addition to being something you tie in a piece of rope or string). In the olden days of sailing they would throw a weighted wooden paddle over the side of the ship. It was attached to a rope with knots tied in it at regular intervals. One person would hold the rope and count how many knots passed though his hand, in a set amount of time. That was how they determined their speed. You are correct that the modern knot is equal to a nautical mile per hour. While they both sound like they come from the same word, a knot refers to speed. In aviation you refer to distance in nautical miles (or just miles)

I stand corrected. I got my knots and 'nauts' mixed up.
My post was all for naught, not that I was trying to be naughty.

Ok try this then.
You are flying in the jet stream. You have a 100 knot per hour tail wind. You do a 180 degree turn. How much ground speed did you just loose? If all the parameters stay the same.

200kts.

It is also still used for maritime and aviation navigation because on a mercator projection chart, 1 nautical mile, is roughly equal to 1 minute of latitude. So it is easy to plot distances using dividers.
