Frequently Asked Questions
Find answers to common questions about Smart Unit Converter
How accurate are the conversions?
All conversions are calculated using precise mathematical formulas and are accurate up to 6 decimal places. We use industry-standard conversion factors to ensure reliability.
Are currency exchange rates updated in real-time?
Currently, currency rates are approximate values. For production use, we recommend integrating a real-time currency API like ExchangeRate-API or Fixer.io for live rates.
Is my conversion history saved?
Yes! Your last 5 conversions are saved locally in your browser using localStorage. This data never leaves your device, ensuring complete privacy.
Can I use Smart Unit Converter offline?
Once the page is loaded, basic conversions work offline. However, you'll need an internet connection to access the site initially and for any future updates.
How do I convert between different unit categories?
Each category (like Length, Weight, Temperature) has its own dedicated converter. Select your category from the homepage, then choose your units and enter the value to convert.
What's the difference between Celsius and Fahrenheit?
Celsius and Fahrenheit are temperature scales. Water freezes at 0°C (32°F) and boils at 100°C (212°F). The formula is: °F = (°C × 9/5) + 32
Why can't I convert meters to kilograms?
Meters measure length while kilograms measure mass - these are different physical quantities and cannot be directly converted. You can only convert within the same category.
How do I copy my conversion result?
Click the 'Copy' button next to your result. The value will be copied to your clipboard for easy pasting elsewhere.
