Frequently Asked Questions
How accurate are the unit conversions?
Our converter uses precise mathematical formulas and factors for all conversions. Results are accurate to 6 decimal places, suitable for most professional and academic applications.
Can I convert between different unit categories?
No, conversions are only possible within the same category (e.g., length to length). Different categories measure different physical quantities and cannot be directly converted.
Why are temperature conversions different?
Temperature scales use different zero points and intervals. Our converter uses specialized algorithms for accurate temperature conversions between Celsius, Fahrenheit, Kelvin, and Rankine.
Is there a limit to the values I can convert?
The converter handles a wide range of values, from very small decimals to large numbers. Extremely large values may be displayed in scientific notation for readability.
Can I use this converter offline?
The converter works entirely in your browser using JavaScript. Once the page loads, all calculations are performed locally without needing an internet connection.
