How accurate are the conversions?

Conversions use the exact SI-standard factors, so results are accurate to full precision and rounded for readability. No approximated ratios are used.

Why does my 1 TB drive show less than 1 TB?

Drive vendors advertise SI terabytes (1,000,000,000,000 bytes) while operating systems often display binary units (TiB). 1 TB equals about 0.909 TiB.

Does the Unit Converter handle currency?

No. Exchange rates change continuously and need a live feed, so currency conversion is better done with your bank or a dedicated finance service.

Is the Unit Converter free and private?

Yes. It is free, requires no account, and all conversions run in your browser — your values never leave your device.

What is the difference between MB and MiB?

MB (megabyte) is 1,000,000 bytes; MiB (mebibyte) is 1,048,576 bytes. The converter makes the convention explicit for data sizes.

Why is there no currency converter?

Exchange rates change continuously and need a live feed. Fixed conversion factors would be wrong within hours, so currency is better handled by your bank or a finance service.

How do I convert temperatures in my head?

For Celsius to Fahrenheit, double and add 30 for a rough figure; the exact formula is °F = (°C × 9/5) + 32. Remember that −40 is the same in both scales.

Is a US gallon the same as a UK gallon?

No. The US gallon is 3.785 litres; the imperial (UK) gallon is 4.546 litres. Always confirm which gallon a recipe or spec means.

How precise should I round converted values?

Round to the precision of your measurement, not the calculator's display. A kitchen-scale weight needs one or two decimals; engineering tolerances need to keep the source's significant figures.

Can the converter handle very large or very small values?

Yes. It accepts scientific notation and extreme magnitudes, converting in full precision without overflow for realistic inputs.
