How do I convert ft/s to km/h?

Multiply the speed in feet per second by one point zero nine seven two eight to get kilometers per hour.

Think of feet per second as how many little foot-long steps happen every second, and kilometers per hour as how many big thousand-meter trips happen every hour. First change feet into meters by remembering one foot equals zero point three zero four eight meters. Then change seconds into hours by knowing one hour has three thousand six hundred seconds, and change meters into kilometers by knowing one thousand meters equal one kilometer. When you combine those three conversions you get a single multiplier, so you can just take the number of feet per second and multiply it by one point zero nine seven two eight to find kilometers per hour.

A common mistake is forgetting to convert seconds into hours, which makes the result far too small; always include the three thousand six hundred seconds per hour factor. Another error is rounding the conversion from feet to meters too roughly, which can add noticeable error in precise problems; use zero point three zero four eight for one foot. Some students try to convert each unit separately every time and lose track of factors, so it helps to multiply all factors at once or memorize the one point zero nine seven two eight multiplier.
