Converting Between Rz & Ra - An educational video by the Machining Doctor

In this video, we'll discuss how to convert between Ra and Rz, two commonly used units in surface roughness measurement. While it's impossible to make an exact conversion between Ra and Rz as you would between Kilowatts and Horsepower, we can use statistical methods to make rough estimates. We'll walk you through the conversion formulas for Ra to Rz and show you how to use a converter tool available on the Machining Doctor website for instant results. Tune in to learn more about converting between Ra and Rz and the best engineering practices to follow.
