About Converting Foot per Minutes to Millimeter per Seconds
Foot per Minutes and Millimeter per Seconds both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Both are distance divided by time units.
Formula
millimeter per seconds = foot per minutes × 5.08
This factor comes from each unit's defined relationship to the category's base unit: 1 foot per minutes equals 0.00508 base units, and 1 millimeter per seconds equals 0.001 base units, so dividing one by the other gives the direct foot per minutes-to-millimeter per seconds factor of 5.08.
Simple example
1 ft/min × 5.08 = 5.08 mm/s
1 foot per minutes = 5.08 millimeter per seconds.
Real-world example
10 ft/min × 5.08 = 50.8 mm/s
10 foot per minutes = 50.8 millimeter per seconds.
