- To convert a number to scientific notation, place or move the decimal point of a number until the coefficient of the number is greater than 1 and less than 10.
- Record down the coefficient ( a) and count the number of steps the decimal point was moved.
- The number of steps moved (n) is taken as the exponent.
- Moving the decimal point to the right gives a negative exponent, whereas moving the decimal point to the left makes a positive exponent.

How do you convert numbers to scientific notation?
To convert any number into scientific notation, you write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.

How do you write 0.25 in scientific notation?
Your number in decimal form is 0.25 . To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, 0.25 becomes 02.5 . The leading zero is not significant, so 02.5 becomes 2.5 .

What is scientific notation?
We learned that scientific notation is a special way scientists use to write very large and very small numbers. You will see some non-zero digits with a decimal place after the first digit multiplied by 10 to a certain power. This power tells you how many digits to move the decimal to get to your number.
How to tell if a decimal is positive or negative?
Another way you can remember whether the power is positive or negative is by the direction you need to move the decimal point . If you need to move it to the left, then your power is positive. If you need to move it to the right, then your power is negative. Let's look at a couple more examples.
What is scientific notation?

What is engineering notation?
Engineering notation. Engineering notation is similar to scientific notation except that the exponent, n, is restricted to multiples of 3 such as: 0, 3, 6, 9, 12, -3, -6, etc. This is so that the numbers align with SI prefixes and can be read as such.

What is scientific notation?
Scientific notation is a way of expressing numbers that are too large or too small (usually would result in a long string of digits) to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard form in the UK.
What is engineering notation?
Engineering notation (often named "ENG" display mode on scientific calculators ) differs from normalized scientific notation in that the exponent n is restricted to multiples of 3. Consequently, the absolute value of m is in the range 1 ≤ | m | < 1000, rather than 1 ≤ | m | < 10. Though similar in concept, engineering notation is rarely called scientific notation. Engineering notation allows the numbers to explicitly match their corresponding SI prefixes, which facilitates reading and oral communication. For example, 12.5 × 10−9 m can be read as "twelve-point-five nanometres" and written as 12.5 nm, while its scientific notation equivalent 1.25 × 10−8 m would likely be read out as "one-point-two-five times ten-to-the-negative-eight metres".
What is a nonzero number?
In scientific notation, nonzero numbers are written in the form. or m times ten raised to the power of n, where n is an integer, and the coefficient m is a nonzero real number (usually between 1 and 10 in absolute value, and nearly always written as a terminating decimal ).
When are the 10 and exponent omitted?
The 10 and exponent are often omitted when the exponent is 0. Normalized scientific form is the typical form of expression of large numbers in many fields, unless an unnormalized or differently normalized form, such as engineering notation, is desired.
Why is it important to record all the definitely known digits from the measurements?
It is customary in scientific measurements to record all the definitely known digits from the measurements, and to estimate at least one additional digit if there is any information at all available to enable the observer to make an estimate. The resulting number contains more information than it would without that extra digit (s), and it (or they) may be considered a significant digit because it conveys some information leading to greater precision in measurements and in aggregations of measurements (adding them or multiplying them together).
What is significant figure?
A significant figure is a digit in a number that adds to its precision . This includes all nonzero numbers, zeroes between significant digits, and zeroes indicated to be significant . Leading and trailing zeroes are not significant because they exist only to show the scale of the number. Therefore, 1 230 400 usually has five significant figures: 1, 2, 3, 0, and 4; the final two zeroes serve only as placeholders and add no precision to the original number.
