How accurate are the conversions?
All conversions use exact or standard SI-based constants. Temperature conversions use the standard formulas (°C = (°F-32)×5/9, K = °C+273.15). Floating-point display is rounded to 10 significant figures.
Does it handle negative temperatures?
Yes — negative Celsius and Fahrenheit values are supported. Note that −273.15°C (0 K) is absolute zero and Kelvin cannot go below 0.
Can I convert units from different categories?
No — units must be in the same physical dimension. You cannot convert meters to kilograms.
