We moved the decimal to the left so b is positive.Move the decimal 5 places to the left to get 3.57096.Remove trailing 0's only if they were originally to the left of the decimal point.Įxample: Convert 357,096 to Scientific Notation.Write your scientific notation number asĪ x 10^b and read it as " a times 10 to the power of b.".If you did not need to move the decimal b = 0. If you moved the decimal to the right b is negative. If you moved the decimal to the left b is positive.Count how many places you moved the decimal point.Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point.b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number. The proper format for scientific notation is a x 10^b whereĪ is a number or decimal number such that the absolute value ofĪ is greater than or equal to one and less than ten or, 1 ≤ | a| < 10.

How to Convert a Number to Scientific Notation For example, 3.4 x 10^5 has an order of magnitude of 5 since 10 is raised to the 5th power. The order of magnitude when written in standard form, is the nth power of 10. Order of magnitude will also be identified for the calculated standard form. You can also enter numbers in e notation.
To enter a number in scientific notation use a carat ^ to indicate the powers of 10. Enter a number or a decimal number or scientific notation and the calculator converts to scientific notation, e notation, engineering notation, standard form and word form formats.
