FAQ
Questions, answered.
Which fuel economy units are supported?
The converter supports 3 units including Kilometers per Liter (km/L), Miles per Gallon (US) (mpg), Miles per Gallon (UK) (mpg) and more, all cross-converted through the Kilometers per Liter base unit.
Are conversions calculated online or in my browser?
Every conversion runs entirely client-side using the Universal Converter Engine. Nothing is uploaded, cached, or logged.
How accurate are the results?
Conversion factors match SI / NIST references. The Precision Engine eliminates float drift and lets you choose 0–12 decimal places, with automatic scientific notation for extreme magnitudes.
Can I export or print the results?
Yes. Every run generates Markdown, CSV, JSON, and plain-text artifacts you can copy, download, print, or share.
