Express a real number in normalized scientific notation as a coefficient times a power of ten. Enter the requested values and select Calculate. The result and supporting values are produced locally in your browser.

Formula

x = a × 10^n, where 1 ≤ |a| < 10 for x ≠ 0

Worked example

1,234,500 is 1.2345 × 10^6 in scientific notation.

What to keep in mind

  • The coefficient magnitude is at least 1 and less than 10 for nonzero values.
  • Scientific notation is useful for very large and very small values.
