The units in which you measure something make little difference as long as you use them correctly, and incorrect or inaccurate usage accounts for much falsity, especially in advertising.

A TV commercial running in my area recently (and very frequently) claims that a particular business is conveniently located "only 6 minutes east of Wichita at 960 miles per hour."

Being in the area recently, I "clocked" the distance and found that the ad is "off by 4.8 seconds." I'm not sure whether to be astonished that they got that close, or annoyed by the error.
