Note that we do not remove the trailing 0 because it was originally to the right of the decimal and is therefore a significant figure.The number 0.000380 converted to standard form is 3.80 x 10 -4.We moved the decimal to the right so b is negative.Move the decimal 4 places to the right and remove leading zeros to get 3.80.The number 459,608 converted to standard form is 4.59608 x 10 5Įxample: Convert 0.000380 to Standard Form.We moved the decimal to the left so b is positive.Move the decimal 5 places to the left to get 4.59608.Remove trailing 0's only if they were to the left of the decimal point.Įxample: Convert 459,608 to Standard Form.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 standard form is mathematically equivalent to the original number. Standard form of a number is a x 10 b whereĪ is a number, 1 ≤ | a| < 10. b is an integer and is the power of 10 required so that the product of the multiplication in standard form equals the original number.a is a number whose absolute value is a decimal number greater than or equal to 1, and less than 10:.Standard form is like scientific notation where a number is represented as a decimal number times a power of 10. Written in standard form this number is equivalent to 6.71 x 10 8. Standard form is like scientific notation and is typically used in science and engineering.Ī number is written in standard form when it is represented as a decimal number times a power of 10.Īs an example, consider the speed of light which travels at about 671,000,000 miles per hour. Scientific Notation Converter converts numbers or expressions into scientific notation and can also convert numbers from scientific notation to ordinary and. It is often used for very large or very small numbers. Standard form is a way of writing a number so it is easier to read. Convert from number format to standard form as a decimal multiplied by a power of 10. Find standard form of a positive or negative number with the standard form calculator.
