Move the decimal point so exactly one non-zero digit is to its left, giving the coefficient (a number from 1 up to but not including 10). Count how many places you moved: that count is the exponent on 10 — positive if the original number was large, negative if it was small. For example, 4500 becomes 4.5 × 10³.

Multiply the coefficient by 10 raised to the exponent: move the decimal point that many places right for a positive exponent or left for a negative one. So 3.2 × 10⁻⁴ becomes 0.00032.

E (or e) notation writes 'times ten to the power' as the letter E, so 6.02 × 10²³ is written 6.02E23. Calculators and programming languages use it because it is plain text. This tool shows both forms.

Engineering notation is like scientific notation but the exponent is always a multiple of 3, so the coefficient can range from 1 up to 1000. It lines up with metric prefixes like kilo, mega, and milli. For example, 47000 is 47 × 10³.

Standard form is another name for scientific notation, used mainly in the UK and many other countries. It means the same thing: a coefficient between 1 and 10 multiplied by a power of ten.
