Just type the number you want and it will automatically do the calculation for you.

### Digit

When converting a number into scientific notation, we must remember a few rules. First, the decimal must be between the first two non-zero numbers. The number prior to the multiplication symbol is known as the significant or mantissa. The numbers of digits in the significant depends on the application and are known as significant figures. The significant figures calculator can assist in this situation. The value of the exponent depends on whether or not the decimal place is moved to the right or left to return to the original number. An example on how to convert a number into scientific notation is done in the next section.

Instead of moving the decimal point to the left in the coefficient, the decimal point needs to be moved to the right until one non-zero significant digit is to the left of the decimal point. Because the number is getting larger, we need to decrement a number from the exponent every time the decimal point is moved. (Source: www.inchcalculator.com)

### Enter

Convert a number to and from scientific notation, e notation, engineering notation, standard form, and real numbers. 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.

To enter a number in scientific notation, first input the argument, then press the EE key and enter the exponent. For example, to enter the mass of the earth, key in 5.97, then press the EE key and enter 24. The display will read 5.97E24 (or 5.97e24). Note that the number will appear with all its zeroes if they fit on the screen. For example, if you key in 1.2 EE 5, the display will show 120,000. (Source:
