Where do you get that ? Just look up some specs. Even a cheap (20 Euro) plastic bubble level can have a sensitivity [1] of 1/2000 (0.03 degrees). Absolute accuracy is easy to check, just turn the level by 180 degrees. Those used by e.g. surveyors (still analog 'bubble') can be orders of magnitude better. Most people have absolutely no idea of how accurate old-school analog things can be. Manufacturing and use of some of those is based on hundreds of years of experience. [1] Sensitivity is the inclination required to move the bubble by one graduation line. Graduation lines are typically 2 mm apart.
