Cube Root Calculator
Calculate the cube root of any number with precision. The cube root of a number is a value that, when multiplied by itself three times, gives the original number. This calculator supports both positive and negative numbers and allows you to adjust the decimal precision of the result.
How to Use the Cube Root Calculator
- Enter the number you want to find the cube root of in the input field
- Select your desired decimal precision from the dropdown menu

What is a Cube Root?
The cube root of a number x is a value that, when multiplied by itself three times (cubed), equals x. For example, the cube root of 27 is 3 because 3 × 3 × 3 = 27. Unlike square roots, cube roots can be calculated for negative numbers as well. The cube root of -8 is -2 because (-2) × (-2) × (-2) = -8.
Common Cube Roots
- ∛1 = 1
- ∛8 = 2
- ∛27 = 3
- ∛64 = 4
- ∛125 = 5
- ∛216 = 6
- ∛1000 = 10
- ∛-8 = -2
