Yeah times 1.6 isn't too hard right? Just add 50% and 10% in succession, very easy to do in your head. The other way around is trickier. I tend to divide by 8

The other way around is trickier. I tend to divide by 8 (or /2/2/2) and multiply by 5, which is harder but still consists only of steps that are clearly defined in my head.
- ilikepi 7y agoYeah, converting via the 5/8 ratio is how I've always done it. I traveled to Florida a number of times as a kid, and for whatever reason I have a permanent memory of the speed limit signs showing "55 MPH / 88 KMH". It's weird what one's brain seems to fixate on sometimes...
