30 cm per second = 0.67 mph
1,497 meters per second = 3,348.7 mph
350 mph = 0.098 miles per second.
16 mph is equal to approximately 23.47 feet per second.
150 miles in 3 hours is equal to 50 mph. 50 mph = 0.0138 miles per second.
One mile per hour is equal to 0.447 meters per second.
240 mph = 352 feet per second.
54 km per second is equal to 120,794.56 mph
220 mph is equal to 322.66658 feet per second.
By fps I assume it feet per second,hence 400fps=272.72727288 mph
1 yps = 3600 yph = 3600/1760 mph = 2.045 mph
To convert miles per hour (mph) to feet per second (fts), you can use the conversion factor where 1 mph is equal to approximately 1.46667 feet per second. Therefore, to convert 3.4 mph to feet per second, you multiply 3.4 by 1.46667, which equals approximately 4.99 fts.
There is not a conversion for mph to hours.
