Frequently Asked Questions
What unit categories are supported?
The tool supports length, weight, volume, temperature, area, speed, and time. Each category includes multiple metric and imperial units.
Is my data sent to a server?
No. All conversion happens locally in your browser. Nothing is transmitted.
How does temperature conversion work?
Temperature uses offset formulas such as °C = (°F - 32) × 5/9, not simple multiplication ratios. The tool handles these special cases automatically.
Can I convert between metric and imperial?
Yes. The tool supports both metric-to-metric and metric-to-imperial conversions within each category.
How precise are the results?
Results are calculated with high precision. The displayed number of decimal places may vary by unit, but the underlying calculation is accurate.
