Conversion questions
Know what the numbers represent.
How does the unit converter work?+
Linear units are converted through a shared base unit using internationally defined factors. Temperature uses separate formulas because its scales have different zero points.
What is the difference between MB and MiB?+
A megabyte is decimal and contains 1,000,000 bytes. A mebibyte is binary and contains 1,048,576 bytes.
Are US and imperial volumes the same?+
No. This converter labels US cooking and liquid units explicitly. Imperial gallons, pints, and fluid ounces use different quantities.
Can I enter negative numbers?+
Yes. Negative values are useful for temperatures and mathematical comparisons. Some physical measurements may not make real-world sense below zero.
Why can the last decimal differ from another calculator?+
Displayed results are rounded to your chosen precision. Increasing precision reveals more of the underlying converted value.
