Scientific Notation
—
Mantissa and power of ten.Usage Tip
The exponent is the order of magnitude: 10^3 is thousands, 10^6 millions, 10^9 billions.
THE MATH
value = mantissa × 10^exponent
The mantissa is at least 1 and less than 10
The mantissa is at least 1 and less than 10
Scientific notation writes very large or small numbers compactly as a mantissa times a power of ten.
It is standard in science and engineering for readability and precision.

Enter a plain number (150000000) or scientific form (1.5e8).
The mantissa is normalized to between 1 and 10.
E-notation (1.5e+8) is the form most calculators display.
