Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on
convert-me.com FaceBook pageThank you for being with us and sorry for any inconveniences this could caused.

how do u get 20mph to feet per second? please give answer!
Wed Jun 22, 2005 7:41 am
20 mi/h x 5280 ft/1 mi x 1 hr/3600 s = 29.33 ft/s
note that 5280/3600 reduces to 22/15 and 22 fps/15 mph can be used directly as a conversion constant.

should that be a division and not multiplication

No, it should not. Write all the divisions (/) as fractions above and below a big horizontal bar. You'll better be able to see the unit cancellation that makes it all work out. The "slashes" make it hard to follow.

Just DIVIDE any MPH by .6818181818 and it will be FPS
Try it: 60MPH / .6818181818 = 88FPS
20MPH / .6818181818 = 29.33FPS

or you could multipy MPHx1.467

1 mph = 1.609 kph = 1.467 fps
