Is this really easier for people than simply multiplying by ⅝ or ⁸⁄₅ as appropriate? And how often does one need to do this conversion anyway? I definitely don’t have any fibonacci numbers above 13 memorized.

I usually just treat miles as kilometers. When I need more precision I multiply miles by 1.5. All these 8/5 just don't stick in my mind, and 1.6 is not much better then 1.6, but it is much easier to multiply by 1.5.

Every time I see distance measured in miles. It may be 1 time per week, or multiple times per day.

>I usually just treat miles as kilometers.

I'll take "things not to say to a cop" for 300 Alex.

Alex isn’t the host any more and there hasn’t been a 300 in a very long time.
