I checked the definition at the webopaedia and micro is millionths. I do believe that you are correct that the interval is thousands, not tens for the next levels. So Micro is 3 orders of magnitude past Milli, Nano is 3 past Micro, Pico is 3 past Nano, etc. I have no idea what the terms are for the fractions between those names are. Not that any of this matters for VFP code execution speed... :)
