Question 1

How accurate is this converter?

Accepted Answer

Factors follow common SI and US customary definitions used in reference tables. JavaScript uses double-precision floats, so extremely long decimals may show tiny rounding differences.

Question 2

Does my input leave my device?

Accepted Answer

No. The page runs entirely in your browser; values are not sent to AnyServ servers for conversion.

Question 3

US vs imperial gallons?

Accepted Answer

Volume presets use US customary cups, fluid ounces and gallons. UK imperial gallons differ; add a category later if you need them.

Question 4

Can I convert currencies here?

Accepted Answer

No - use the Currency Converter for money. This tool is for physical units only.

Question 5

What about data and energy units?

Accepted Answer

This version focuses on everyday length, mass, volume, temperature, area and speed. More categories can be added over time.
