Example

0. 0000000345 → 3. 45 × 10⁻⁸

Formula

number = a × 10^b (where 1 ≤ |a| < 10)

Move the decimal point until the coefficient is between 1 and 10. The number of places moved becomes the exponent b.

Negative exponent for numbers < 1

Check

Writing 123 × 10³ instead of 1. 23 × 10⁵
Confirm that all inputs use the same unit system expected by the formula.

FAQ

Why is the coefficient required to be between 1 and 10?

It's the international standard — makes numbers consistent and easy to compare magnitudes.

How do you handle negative numbers?

The minus sign stays with the coefficient: -4. 56 × 10⁴
