What is scientific notation converter?
A scientific notation converter is a tool that allows you to convert numbers from standard notation (also known as decimal notation) to scientific notation (also known as exponential notation), and vice versa. Scientific notation is a way of expressing very large or very small numbers in a more compact form, making them easier to read and work with.
In scientific notation, a number is written as a coefficient multiplied by a power of 10. The coefficient is usually a number between 1 and 10, and the power of 10 indicates how many places the decimal point has been moved to the left or right.
For example, the number 123,000,000 can be written in scientific notation as 1.23 x 10^8. The coefficient is 1.23, and the power of 10 is 8, which indicates that the decimal point has been moved 8 places to the right.
A scientific notation converter allows you to easily convert between standard notation and scientific notation. To use the converter, simply enter the number you want to convert into the appropriate field, and the converter will display the number in both standard notation and scientific notation.
How to write in scientific notation?
To write a number in scientific notation, you can follow these steps:
- Move the decimal point in the original number so that there is only one non-zero digit to the left of the decimal point. For example, if you have the number 123,000, you would move the decimal point 3 places to the left to get 1.23.
- Count the number of places you moved the decimal point. This will be the exponent of 10 in the scientific notation. If you moved the decimal point to the left, the exponent will be positive. If you moved it to the right, the exponent will be negative. For example, in the number 1.23, you moved the decimal point 3 places to the left, so the exponent will be 3.
- Write the number in scientific notation by writing the coefficient (the number you got in step 1) followed by “x 10^” and the exponent (the number you got in step 2). For example, the number 123,000 in scientific notation would be written as 1.23 x 10^5.
Another example: Let’s say you have the number 0.0000678. To write this number in scientific notation, you would move the decimal point 5 places to the right to get 6.78. The exponent will be negative 5 (since you moved the decimal point to the right). Therefore, the number in scientific notation would be written as 6.78 x 10^-5.
Note that the coefficient should always be a number between 1 and 10, and the exponent should be an integer (positive or negative). If necessary, you can adjust the coefficient and exponent to meet these requirements while still representing the same value.
Write the number 256,000,000 in scientific notation.
- Move the decimal point so there is only one non-zero digit to the left of the decimal point. This would give us 2.56.
- Count the number of places we moved the decimal point. We moved it 8 places to the left, so the exponent will be 8.
- Write the number in scientific notation as 2.56 x 10^8.
Therefore, 256,000,000 written in scientific notation is 2.56 x 10^8.
