Frequently Asked Questions

How accurate are the unit conversions?

Our unit converter uses precise conversion factors and industry-standard formulas to ensure accuracy up to 15 decimal places. All conversions are based on internationally recognized standards.

Does the converter work offline?

Yes! All conversions are performed locally in your browser using JavaScript. No internet connection is required after the initial page load, ensuring privacy and speed.

What unit systems are supported?

We support metric (SI), imperial, US customary, and various scientific unit systems. This includes common units like meters/feet, kilograms/pounds, Celsius/Fahrenheit, and many specialized units.

Can I convert between different measurement types?

No, you can only convert within the same measurement type (e.g., length to length, weight to weight). Converting between different types of measurements (like length to weight) is not physically meaningful.
