the methodology of measurement and what is measured are quite different. This is critical to understand if you will not be paid for your parts because the Ra you measured is not in fact the Rz surface profile that customer specified.

Ra equals 0.8 µm?
Ra is the roughness of the surface used in engineering. Mu(greek letter)metres is one millionth of a metre. To put in perspective glass would be around Ra 0.1, polished chrome plating would be around Ra 0.3 so Ra 0.8 is still fairly smooth but a dull finish. You would just be able to feel the surface with your fingernail.

Are hours a ratio or interval level of measurement?
An hour is a unit of measurement. A ratio is a comparison of similar things. You can use hours within a ratio showing something over a measurement of time. For example as speed (25 miles/kilometers per hour) or hourly wages ($7.25 per hour). An hour can also be a measurement of Right Ascension. This is a measure timing the passage of objects in the sky across the meridian as the Earth rotates. RA is measured in hours, minutes, and seconds.
