Frequently asked questions
How does the unit converter work?⌄
Select a category, source/target units, and enter a value. Conversion uses standard formulas instantly. Temperature uses specific non-linear formulas.
Is temperature conversion accurate?⌄
Yes — uses exact formulas: °F = (°C × 9/5) + 32, K = °C + 273.15. Not simple multiplication because temperature scales have different zero points.
What data storage units are used?⌄
Binary (IEC) prefixes: 1 KB = 1024 B, 1 MB = 1024 KB. Used in computing for RAM and file sizes. Some manufacturers use decimal (1 KB = 1000 B).
Can I use scientific notation?⌄
Yes — enter values like 1.5e6 for 1,500,000. Results display appropriately for the magnitude.
