How does A-level work?

For the most part, levels are rectangular objects outfitted with one or more liquid vials. Inside the vial, the bubble is what's used to measure angles. When the bubble is centered in the vial, the angle is correct. Depending on the direction of the vial within the tool, the bubble will measure level, plumb, or 45°.

How do bubble levels work?

If it's centered between the lines on the tube, your object is level. If the bubble is to the right of the lines, your object slopes downward right-to-left. If the bubble is to the left of the lines, your object slopes downward left-to-right. To find the true vertical or "plumb," repeat the same process vertically.
