There isn't any one general answer. It depends on what unit you want to convert to what other unit.
If two functions are the inverse of each other, they reverse or undo what the other function does. To give the simplest example, addition and subtraction are inverse functions, so that if you start with 7 and add 3 you get 10, and then if you subtract 3 you are back to 7, which is what you started with, so the subtraction reverses the effect of the addtion (if you subtract the same amount, which in this example was 3).
You can convert logarithms of different bases to the same base. After that, you may or may not be able to simplify the resulting expression. Example of change-of-base: log21024 = ln(1024) / ln(2) Instead of natural logarithms, you can convert to any other base: log21024 = log10(1024) / log10(2)
That depends what you want to "solve" for - in other words, what the question is. For example, whether you want to:* Convert from hexadecimal to decimal* Convert from decimal to hexadecimal* Count in hexadecimal* Add hexadecimal numbers* etc.
Meter is a unit of length already, so it isn't quite clear what you want to convert. If you have the length in some other unit, multiply or divide by the corresponding conversion factor. For example, if the length is specified in centimeters, you divide by 100 to convert to meters.
