This is a relativly simple page that is intended to help understand how a value in one dimension, relates to a value in another dimension. (e.g. how Megohms relates to Kilohms or Ohms). The "≡" symbol in the table signifies "is equivalent to".
The calculators on the right allow you to enter a electical property using one dimension and see that value with other dimensions.
When a number gets too large to display in limited space, it is displayed in Engineering notation. Engineering notation is similar to Scientific notation in that, they both rewrite values into a form more readable and manageable. Scientific notation displays a number as a value between one and 10, but not including 10, multiplied by a power of 10 (e.g. 12,340,000 might display as 1.234 × 107 or 0.0000001234 might display as 1.234 × 10-7).
Whereas, Engineering notation displays a number as a value between one and 1000 multiplied by a power of 10, in increments of 3 (e.g. 12,340,000,000 might display as 12.34 × 109 or 0.0000001234 might display as 123.4 × 10-9). This means that the powers of 10 are only the values 3, 6, 9, 12, ... or -3, -6, -9, -12, etc.

In the field of Engineering, number prefixes follow the metric system, like tera, giga, mega, kilo, micro, nano, and pico, differ in size from the next highest or lowest prefix by 103. This is illustrated in the table on the left. A table similar to this one is in The ARRL Handbook for Radio Amateurs. But, in my table, I left out the metric prefixs and symbols that do not have a exponent divisible by 3.
