FAQ
Which units can I convert?
The calculator includes leading length, area, volume, mass, speed, and temperature units. Change the category to instantly recompute the table across every unit in that group.
Can I share my conversion?
Use the “Copy result URL” button to generate a link. When someone opens it, the value and units are restored automatically so they can see the same results.
How is precision handled?
We compute using double‑precision floats. The table rounds for readability; use “Copy results” to get the numeric value with full precision.
Can I add custom units?
Not at this time. The calculator supports common SI and US customary units for each category.
