Frequently Asked Questions
How accurate are the conversions?
All conversions use standard, internationally recognized conversion factors. The results are accurate to at least 6 significant figures, which is more than sufficient for most practical applications. For scientific work requiring extreme precision, always verify with official standards.
Why do temperature conversions work differently?
Unlike other units, temperature scales don't have a simple multiplicative relationship. Celsius and Fahrenheit have different zero points and different sized degrees. Our converter handles these non-linear conversions correctly using the proper formulas: °F = (°C × 9/5) + 32 and °C = (°F - 32) × 5/9.
What's the difference between metric and imperial units?
The metric system (meters, kilograms, liters) is based on powers of 10 and is used by most countries worldwide. The imperial system (feet, pounds, gallons) is primarily used in the United States and has historical origins in British measurements. Our converter handles both systems seamlessly.
Can I convert between any two units?
You can convert between any two units within the same category (e.g., any length unit to any other length unit). However, you cannot convert between different categories (e.g., meters to kilograms) as they measure fundamentally different quantities.
Why are data sizes in powers of 1024 instead of 1000?
In computing, data sizes traditionally use binary (base-2) calculations, where 1 KB = 1024 bytes (2^10), not 1000 bytes. This is because computers work in binary. Our converter uses the binary standard (1024) which is the most common convention in computing.
Is my data saved or sent to a server?
No! All conversions happen entirely in your browser using JavaScript. Your input values and conversion results never leave your device or get sent to any server. This ensures complete privacy and works even offline once the page is loaded.
