### Should you use the common logarithm or the natural logarithm?

The natural logarithm is the logarithm having base e,
where
The common logarithm is the logarithm to base 10.
It really depends on the question!
Maybe you should check out the examples!
++++
The common, or Base-10, logarithm will cover any multiplication,
division and power arithmetic in the ordinary numbers, which are to
base-10. It is also the base for the logarithmic ratio defining the
decibel scale used in acoustics and electrical signals
analysis.

The natural logarithm (base-e) underlies a large number
of specific scientific laws and purposes, such as the expansion of
gas in a cylinder.

### Show me the meaning of LN?

LN is typically the syntax used to represent the natural
logarithm function. Although some programming languages and
computer applications use LOG to represent this function, most
calculators and math textbooks use LN. In use, it would look like
this:
y=ln(x)
Which reads as "y equals the natural logarithm of x".
The natural logarithm is a logarithm that has a base of
e, Euler's number, which is a mathematical constant
represented by a lowercase italic e (similar to how pi is a
constant represented by a symbol). Euler's number is approximately
equal to 2.718281, although it continues on far past six decimal
places.
Functionally, the natural logarithm can be used to solve
exponential equations and is very useful in differentiating
functions that are raised to another function. Typically, when the
solution to an equation calls for the trivial use of a logarithm
(that is the logarithm is only being used as a tool to rewrite the
equation), either the natural logarithm or the common logarithm
(base 10) is used.

###### Asked in Physics

### What does ln stand for in the Steinhart hart equation?

"Ln" in that equation is the "natural logarithm" of a
number.
The "common logarithm" ... log(x) ... is the logarithm of 'x' to
the base of 10.
The "natural logarithm" ... ln(x) ... is the logarithm of 'x' to
the base of 'e'.
'e' is an irrational number, known, coincidentally, as the "base
of natural logarithms".
It comes up in all kinds of places in math, physics,
electricity, and engineering, especially in
situations where the speed of something depends on how far it
still has to go to its destination.
'e' is roughly 2.7 1828 1828 45 90 45 ... (rounded)
