LOG Formula Syntax
Example Use Case
Calculating the logarithm with a custom base for scaling or comparison
Understanding the LOG Formula
The LOG function in Excel computes the logarithm of a number with a specified base, offering flexibility beyond LN’s natural log or LOG10’s base-10. It’s great for scaling data, comparing growth rates, or analyzing logarithmic relationships tailored to your needs.
LOG(100, 10) returns 2, since 10^2 = 100. It takes two arguments: the number and the base (default is 10 if omitted), making it versatile for custom logarithmic scales in science, finance, or education.
Why Use LOG?
LOG adapts to any base, perfect for specialized analysis—like base-2 for binary systems or base-5 for unique scaling. It’s a flexible tool for dissecting exponential patterns, giving you control over the logarithmic lens.
Example with Sample Data
| Number, Base | Formula | Result |
|---|---|---|
| 100, 10 | =LOG(100, 10) | 2 |
| 8, 2 | =LOG(8, 2) | 3 |
| 25, 5 | =LOG(25, 5) | 2 |
LOG flexes its bases: 100 (base 10) is 2, 8 (base 2) is 3. It’s a custom log calculator.
