Standard form practice
Free, infinite standard form practice. Convert ordinary numbers to a × 10ⁿ and back, then open orders of magnitude when you are ready. Instant feedback.
Start your standard form practice
Our standard form practice tool generates unlimited conversions. Easy mode uses large whole numbers such as 3000 = 3 × 10³. Medium uses small decimals such as 0.0045 = 4.5 × 10⁻³. Hard asks you to convert a × 10ⁿ back to an ordinary number. When you can convert fluently, use the related orders of magnitude practice to compare sizes and powers of ten.
Why standard form practice matters
Compact numbers
Standard form writes very large and very small numbers as a × 10ⁿ with 1 ≤ a < 10. Standard form practice makes that rewrite automatic.
Science and exams
Physics, chemistry, and GCSE maths all use standard form. Daily standard form practice prepares you for both.
Orders of magnitude
Once you can convert, compare exponents. Related orders of magnitude practice asks which is larger and how many times larger.
Standard form practice for students
Start with standard form practice, then use the related orders of magnitude practice to compare 3 × 10⁴ and 2 × 10⁵. Easy, medium, and hard levels keep conversions bounded and reproducible.
Drills and exercises
Easy
3000 = 3 × 10³
Medium
0.0045 = 4.5 × 10⁻³
Hard
3.2 × 10⁴ = 32000
