Convert a plain decimal number into scientific notation, or expand scientific notation back into a standard number, in one tool. Scientific notation writes a value as a number between one and ten times a power of ten, which makes very large and very small quantities readable, like writing three hundred million as three times ten to the eighth. It is standard in science, engineering, and any field dealing with extreme scales. Type an ordinary number to see its scientific form and the compact E-notation used by calculators and code, or type a number with an exponent to expand it back to full digits. It handles negatives and tiny fractions correctly. Everything is computed locally in your browser, so conversions are instant and nothing you enter is sent anywhere.

E-notation is a compact form where 5.3 times 10 to the power 3 is written as 5.3E3, and the tool shows this form too.
