Use our degrees to mm calculator to convert angular measurements in degrees to linear measurements in millimeters (mm). For example… 90 degrees to mm: Using the same circle (radius 100 mm), a 90-degree arc would be about 157.08 mm long. The general formula is: mm = (2 π r * θ) / 360. Where:
and, with α being the same angle measured in degrees, since θ = α 180 π, the arc length equals. A practical way to determine the length of an arc in a circle is to plot two lines from the arc's endpoints to the center of the circle, measure the angle where the two lines meet the center, then solve for L by cross-multiplying the statement:
