Loga-

When I first wrote this on 12^th April 2018 I used 10 as the base for the logarithm. However, on reflection a mere 5 years later I now think the base should be 10^¹⁄₁₀. This has the effect that the rule is simpler: multiply the value by 10, add 10 to the log of the value. Much simpler.

We use unit prefixes (eg kilo) at lot. They’re very useful but there isn’t one to cover them all. Just for fun I thought I might create my own alternate prefix to fill this need:

I present the Loga (from the Greek λογάριθμος, literally a logarithm) with the prefix λ.

This differs from all the other prefixes in that for any unit:

𝑥 Loga-Unit = log_{10^¹⁄₁₀} 𝑥 Unit

The convertion table to the normal prefixes tooks like this:

By way of example, I’ve add the converstions for a few units.
