Do these converters upload my inputs?
No. UnitQuickTools runs conversions and daily calculations in your browser. The numbers and dates you enter are not sent to an application server.
Why is my result rounded?
The tool defaults to four decimal places for readability. You can increase or reduce decimals from the settings panel.
Can it calculate time past midnight?
Yes. If the end time is earlier than the start time, the calculator treats the end as the next day.
