The least count of a bevel protractor can be determined by examining its smallest graduated division. Typically, this is found by measuring the smallest angle that can be read directly from the scale, which is often 1 degree or smaller, depending on the specific design of the protractor. To find the least count, divide the value of the smallest division by the number of divisions on the main scale. For example, if the smallest division is 1 degree and there are 10 divisions, the least count would be 0.1 degrees.
universal bevel protactor is an angle measuring instrument which measures acute angle ,obtuse angle as well as it is used to layout an angle. its least count is 5 minute.
5 min
The least count of a vernier bevel protractor is typically 5 minutes or 0.083 degrees. This means it can measure angles with an accuracy of 5 minutes or 0.083 degrees.
It is 5 mins. Formula : Smallest Division on Main Scale / Number of divisions on Vernier Scale = 1 degree / 12 = 60 mins / 12 = 5 mins.

When inserting a needle, the needle is inserted bevel up.However, at least 1 study suggests (in the same article) that bevel down may help on difficult sticks, on pediatric or dehydrated adults.
