# LOG10

The `LOG10` function returns the base 10 logarithm of a given number. It is commonly used in mathematical and scientific calculations.

## Usage

Use the `LOG10` formula with the syntax shown below, it has 1 required parameter:

Parameters:
1. value (required):
The positive real number or cell reference to the cell containing the number for which you want to calculate the logarithm.

## Examples

Here are a few example use cases that explain how to use the `LOG10` formula in Google Sheets.

### Calculating pH

The pH of a solution is calculated as the negative base 10 logarithm of the molar concentration of hydrogen ions in the solution. You can use the `LOG10` function to calculate the pH of a solution given its hydrogen ion concentration.

### Scaling data

You can use the `LOG10` function to scale data that covers a large range of values. Taking the logarithm of the data can compress the range of values and make it easier to work with.

### Visualizing data

The `LOG10` function can also be used to create visualizations of data that cover a large range of values. By taking the logarithm of the data, you can create a more even distribution of values that is easier to visualize.

## Common Mistakes

`LOG10` not working? Here are some common mistakes people make when using the `LOG10` Google Sheets Formula:

### Using a non-positive argument

The LOG10 function only works with positive numbers. If the argument is non-positive, the function returns an error. Make sure the argument is a positive number.

### Using non-numeric values

The LOG10 function only works with numeric values. If the argument is non-numeric, the function returns an error. Make sure the argument is a numeric value.

### Using the wrong argument order

The LOG10 function only takes one argument, which is the value to be evaluated. If you provide more than one argument or put them in the wrong order, the function returns an error. Make sure you only provide one argument and it is in the correct order.

The following functions are similar to `LOG10` or are often used with it in a formula:

• `LOG`

The `LOG` function in Google Sheets returns the logarithm of a given number to a specified base. This function is commonly used in mathematical and financial calculations.

• `LN`

The `LN` formula returns the natural logarithm of a given value. The natural logarithm is the logarithm to the base e, where e is an irrational number approximately equal to 2.71828. The formula is commonly used in mathematical and scientific calculations.

• `EXP`

The `EXP` function returns the result of e raised to the power of a given exponent. This function is commonly used in mathematical and scientific calculations.

• `POW`

The `POW` formula is a mathematical operator in Google Sheets used to raise a base number to the power of an exponent. It returns the result of the calculation. This formula is commonly used in financial analysis, engineering, and scientific research.

• `SQRT`

The `SQRT` function returns the positive square root of a given number. It can be used to find the length of a side of a right triangle, or to calculate standard deviation. The function takes one argument, the value or reference to the cell containing the number for which you want to find the square root.
