# Taper Degree Calculator

Taper Degree is the central angle of the taper measured in degrees. It can be calculated from the taper % or it can be calculated with the number of the different type of tapers. For instance, a #2 morse taper has an angle of 2.86133 degrees. Use this online calculator to find the taper angle.

#### Formula:

Taper = (dl - ds) / Length
Taper Angle = atan(0.5 x Taper)
**Where,**
dl = Large End Dimension
ds = Small End Dimension

#### Example

A 20 inch taper with small and large diameter as 5 inch and 10 inch has a taper length of 0.25 inch.

**What is the angle formed by a 0.25 inch taper?**

= atan (0.5 x 0.25)

= atan (0.125)

Taper angle=0.124 radians,7.125 in degrees.
