FAQ

Common Questions

Frequently asked questions regarding measurement standards, precision offsets, conversion factors, and privacy.

What conversion standards does this tool follow?
The converter uses standard international unit multiplier factors based on the International System of Units (SI) and standard Imperial measurements.
How does the tool handle temperature conversions?
Temperature conversions (Celsius, Fahrenheit, Kelvin) use custom linear algebraic formulas (e.g. (C * 9/5) + 32 for Fahrenheit) rather than simple multiplicative scales, ensuring correct zero-point offsets.
How many decimal places of accuracy are supported?
The tool defaults to displaying up to 6 decimal places to prevent standard JavaScript floating-point errors, but calculations are kept at double-precision internally.
Can I convert digital storage units like Megabytes to Gigabytes?
Yes. The tool includes a "Data Storage" category supporting standard binary (1024 base) and decimal (1000 base) conversions for bytes, kilobytes, megabytes, gigabytes, and terabytes.
Are my calculations uploaded to your servers?
No. The unit conversion engine runs entirely client-side using JavaScript in your web browser. None of your measurements or conversions are sent to our servers.
