Division
1.
Set the number you are dividing by on the inner scale over the number you
are dividing on the outer scale. (e.g., for 540 ÷ 12 = 45, set the 12 on the
inner scale over 54 on the outer scale.)
2.
Read the result on the outer scale opposite the (10/arrow) number on the
inner scale.
Ratios and Conversions
When the numbers on the outer scale and the inner scale match, the ratio
between the two scales is 1:1. When you rotate the inner scale so that the
number (10/arrow) is opposite the 20 on the outer scale, the ratio between
the two scales is 2:1. This feature is useful to convert any linear conversion
like currencies or weight/length from standard to metric. Simply find how
many units of one measurement equals one unit of the other and match up
that number with the number (10/arrow).
