Now I am curious. What kind of calculations can you do except divide by
60?

Now *I'm* curious, did you not realize how it is an E6B accomplishes "divide
by 60"?

The core of an E6B is simply a circular slide rule. As with a basic linear
slide rule, you have two logarithmic scales that allow you to perform any
multiplication or division you like.

The "60" is highlighted, and the regular logarithmic scale is paralleled by
a conversion from minutes to hours. This makes time-speed-distance
calculations even easier. But they don't restrict your use of the slide
rule.
