How to Use This Calculator
- Enter a number in the input field.
- Select the base of the logarithm from the dropdown menu.
- Click the ‘Calculate’ button.
- View the result in the ‘Results’ section.
Formula & Methodology
The formula for calculating a logarithm is:
logb(a) = c where b is the base, a is the number, and c is the result.
Our calculator uses the following methods to calculate the logarithm:
log10(a)is calculated using the formulalog(a) / log(10).log2(a)is calculated using the formulalog(a) / log(2).loge(a)is calculated using the formulalog(a).
Real-World Examples
Example 1: Finding the base 10 logarithm of 1000
Using our calculator, enter 1000 and select ‘Base 10’. The result is 3, which means 10^3 = 1000.
Data & Statistics
| Number | Base 10 | Base 2 | Base e |
|---|---|---|---|
| 1000 | 3 | 9.96578 | 6.90776 |
| 1000000 | 6 | 19.93157 | 6.90776 |
Expert Tips
- Understand the difference between common (base 10) and natural (base e) logarithms.
- Remember that the logarithm of 1 is always 0, regardless of the base.
- To find the base of a logarithm, use the change of base formula:
logb(a) = logc(a) / logc(b).
