LOG10 Function is a mathematical function in Excel that allows you to calculate the base 10 logarithm of a number. It’s a useful tool for working with data that follows exponential or logarithmic patterns, and it can help you analyze and manipulate such data effectively.

## Syntax

**LOG10(number)**

## Arguments

number | The positive real number for which you want to calculate the base 10 logarithm. |

## How to Use

The LOG10 function is straightforward to use. You simply provide it with the number for which you want to find the base 10 logarithm. Here’s a step-by-step guide and some examples to help you understand how to use this function.

**Step 1:** Start by selecting the cell where you want the result to appear.

**Step 2:** Begin the formula with an equal sign, followed by the function name LOG10.

**Step 3:** Inside the parentheses, enter the number for which you want to calculate the base 10 logarithm.

**Step 4:** Close the parentheses and press Enter.

For example, if you want to find the base 10 logarithm of the number 100, you would use the formula

1 |
=LOG10(100) |

The result will be displayed in the selected cell, which in this case will be 2, as LOG10(100) equals 2, since 10^2 equals 100.

Here are a few more examples to illustrate the use of the LOG10 function:

1 |
=LOG10(1) |

This will return 0 because 10^0 equals 1.

1 |
=LOG10(1000) |

This will return 3 because 10^3 equals 1000.

## Additional Information

The LOG10 function is particularly useful in scientific and financial calculations, as well as when dealing with data analysis. It helps in transforming data to better understand patterns, relationships, and scale.
