Unit convertersA useful starting point
Unit conversion is only useful when the unit definition and direction are obvious. LittleKit puts the two directions side by side, keeps the calculation in the browser and shows the precision used for the displayed result.
Good reasons to use this category
- Converting a measurement while planning or building
- Checking storage and transfer-rate units
- Moving between metric and imperial conventions
- Copying a result into another document
Choosing the right operation
Confirm whether a value is decimal or binary before converting it. In particular, storage units such as GB and GiB are not interchangeable, and fuel economy can be expressed as either distance per volume or volume per distance. The unit labels are part of the answer.
Know the boundary
Conversions use named definitions and double-precision arithmetic. Rounding is for display; it does not turn an estimate into a measurement. For regulated, engineering or safety-critical work, confirm the applicable standard and significant figures.
