Scientific Notation Converter

Q: What is 0.00034 in scientific notation?

0.00034 = 3.4 × 10⁻⁴. Move the decimal 4 places to the right to get 3.4, so the exponent is -4.

Q: What is 5.6 × 10³ in standard form?

5.6 × 10³ = 5,600. Move the decimal 3 places to the right.

Q: How do you multiply numbers in scientific notation?

Multiply the coefficients and add the exponents. Example: (2 × 10³) × (3 × 10⁴) = (2 × 3) × 10^(3+4) = 6 × 10⁷.

Convert any number to scientific notation (standard form), or convert scientific notation back to a regular number. Supports E notation.

What is Scientific Notation?

Scientific notation expresses numbers as a × 10ⁿ where 1 ≤ |a| < 10. It's used in science to write very large or very small numbers compactly. For example, the speed of light is 3 × 10⁸ m/s, and an electron's mass is 9.11 × 10⁻³¹ kg.

How to Convert to Scientific Notation

Move the decimal point until only one non-zero digit is to the left of it. Count the moves — right moves give a negative exponent, left moves give a positive exponent.
