About Converting Maches to Foot per Days
Mach and Foot per Days both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Specifically: Mach at standard sea-level conditions, and distance divided by time.
Formula
foot per days = maches × 96460157.4803
This factor comes from each unit's defined relationship to the category's base unit: 1 mach equals 340.29 base units, and 1 foot per days equals 0.00000352777777778 base units, so dividing one by the other gives the direct mach-to-foot per days factor of 96460157.4803.
Simple example
1 Ma × 96460157.48 = 96,460,157.48 ft/d
1 mach = 96,460,157.48 foot per days.
Real-world example
10 Ma × 96460157.48 = 964,601,574.8 ft/d
10 maches = 964,601,574.8 foot per days.
