Calculating powers of 10 is a fundamental mathematical operation that appears in many scientific, financial, and everyday contexts. Whether you're working with scientific notation, understanding large numbers, or performing calculations in fields like physics or engineering, knowing how to put 10 to the power in a calculator is essential.
How to Calculate Powers of 10
Calculating powers of 10 involves multiplying 10 by itself a specified number of times. The general formula is:
10n = 10 × 10 × ... × 10 (n times)
Where n is the exponent (the number of times 10 is multiplied by itself).
For example, 103 means 10 multiplied by itself three times:
103 = 10 × 10 × 10 = 1,000
Positive Exponents
When the exponent is positive, you multiply 10 by itself the specified number of times. For example:
- 101 = 10
- 102 = 100
- 104 = 10,000
- 106 = 1,000,000
Negative Exponents
When the exponent is negative, the result is the reciprocal of the positive exponent. For example:
- 10-1 = 1/10 = 0.1
- 10-2 = 1/100 = 0.01
- 10-3 = 1/1,000 = 0.001
Zero Exponent
Any non-zero number raised to the power of 0 is 1. This is a special case:
100 = 1
Using a Calculator for Powers of 10
Most scientific and graphing calculators have a built-in exponent function that makes calculating powers of 10 quick and easy. Here's how to use it:
- Turn on your calculator and ensure it's in the appropriate mode (usually "Sci" for scientific mode).
- Enter the base number (10).
- Press the exponent button (often labeled as "xy" or "^").
- Enter the exponent (the power to which you want to raise 10).
- Press the equals (=) button to see the result.
If your calculator doesn't have an exponent button, you can also use the multiplication function to calculate powers of 10 by multiplying 10 by itself the specified number of times.

Common Examples of Powers of 10
Powers of 10 are used in many contexts, from measuring distances to expressing very large or very small numbers. Here are some common examples:
| Exponent | 10 to the Power | Common Usage |
|---|---|---|
| 101 | 10 | Basic counting |
| 102 | 100 | Square meters, centimeters |
| 103 | 1,000 | Kilometers, millimeters |
| 106 | 1,000,000 | Megabytes, kilometers |
| 109 | 1,000,000,000 | Gigabytes, kilometers |
| 10-1 | 0.1 | Decimeters, tenths |
| 10-3 | 0.001 | Millimeters, thousandths |
FAQ
What is the difference between 10 to the power of 2 and 10 to the power of 3?
10 to the power of 2 (102) equals 100, while 10 to the power of 3 (103) equals 1,000. The difference is that 10 is multiplied by itself one additional time in the third power.
How do I calculate 10 to the power of a negative number?
To calculate 10 to the power of a negative number, take the reciprocal of 10 to the positive power. For example, 10-2 equals 1/100 or 0.01.
Why is 10 to the power of 0 equal to 1?
Any non-zero number raised to the power of 0 is equal to 1. This is a mathematical rule that applies to 10 as well. It's based on the concept of division by itself, which always equals 1.
Can I use a calculator to find powers of 10?
Yes, most scientific and graphing calculators have an exponent function that makes calculating powers of 10 quick and easy. You can also use the multiplication function to calculate powers of 10 by multiplying 10 by itself the specified number of times.
