Step 1: Describe Your Formula

0/120

Step 2: Copy Syntax

LOG formula syntax.

The LOG function in Excel is used to calculate the logarithm of a number to a specified base. The syntax for the LOG function is as follows: LOG(number, base) - "number" is the positive real number for which you want to calculate the logarithm. - "base" is the base of the logarithm. If omitted, the default base is 10. The LOG function returns the logarithm of the number to the specified base.

Use Cases & Examples In these use cases, we use the LOG function to calculate the logarithm of a number with a specified base. The LOG function is commonly used in various mathematical and scientific calculations to determine the exponent to which a specified base must be raised to obtain a given number.

Calculating Compound Interest

Description

This use case demonstrates how to calculate compound interest using the LOG function. Compound interest is calculated by multiplying the principal amount by one plus the interest rate raised to the power of the number of periods. The LOG function is used to calculate the power of the interest rate.

Result

=principal_amount * (1 + interest_rate) ^ (LOG(number_of_periods, 10) / LOG(1 + interest_rate, 10))

Calculating Decibel Level

Description

This use case demonstrates how to calculate the decibel level using the LOG function. Decibel level is a logarithmic scale used to measure the intensity of sound or the power of an electrical signal. The LOG function is used to calculate the logarithm of the ratio of the measured value to the reference value.

Result

=20 * LOG(measured_value / reference_value, 10)

Calculating pH Level

Description

This use case demonstrates how to calculate the pH level using the LOG function. pH level is a measure of the acidity or alkalinity of a solution. The LOG function is used to calculate the negative logarithm of the hydrogen ion concentration.

Result

=-LOG(hydrogen_ion_concentration, 10)
