It is the degree measure of the runway. If the runway is going due south, then it is 180 degrees on the compass. Remove the 0 to get runway 18. Then if there are other 18s, then they are labeled Left, Center, Right. 18L, 18C, 18R.

Not quite. It is the orientation divided by ten, which is rounded to the nearest whole number. A runway whose orientation is 157 degrees would not be runway 160, but runway 16, which is 15.7 rounded to the nearest whole number.Alternatively, you could round to the orientation to the nearest ten and then divide by 10.

Magnetic North. Runway numbers and letters are determined from the approach direction. The runway number is the whole number nearest one-tenth the magnetic azimuth of the centerline of the runway, measured clockwise from the magnetic north. - Aeronautical Information Manual (AIM) 2-3-3 b.
White runway marking snd yellow runway hold lines.
Runway markings are white. Runway hold lines are yellow.
Factors like altitude and temperature can effect the required runway. The website below provides the recommended runway for a number of poplular private jets. There are also graphs comparing the preformance to other aircraft in a specific category.
The runway numbers are in magnetic direction. Runway 27 is 270 degrees magnetic (rounded off to the nearest 10 degrees). Runway 04 is 040 degrees magnetic. When you are making your approach, your runway of intended use (into the wind) will be your magnetic direction on your compass. When you see an L, C, or R after the number there would be two or more runways in the same direction on that airport. The letters stand for Left, Center, or Right depending on which runway you would be assigned to land on. As runways can be approached from either direction the difference between the two number will reflect the 180° difference, thus increments of 18.
