What this calculator helps you do
Scientific notation makes very large and very small numbers easier to read and compare. This calculator helps you convert between standard form and scientific notation and check arithmetic involving powers of ten.
How scientific notation works
A number written in scientific notation has two parts: a coefficient and a power of ten. For example, 4.2 x 10^6 means 4,200,000, while 7.5 x 10^-3 means 0.0075.
Worked example
To convert 0.00056, move the decimal 4 places to the right to get 5.6. That gives 5.6 x 10^-4.
