Work out standard form to ordinary number instantly with clear inputs, formula shown and shareable results.
Standard form writes a number as a × 10ⁿ with 1 ≤ |a| < 10. Converting back means shifting the decimal point n places right for positive n and left for negative n.
Standard form
value = a × 10ⁿ, 1 ≤ |a| < 10
456000 — shift the point five places to the right.
