FAQ
How accurate are these conversions?
We use standard, widely accepted conversion factors for high accuracy. However, for critical applications requiring extreme precision, always consult authoritative sources. Rounding differences may occur depending on the number of decimal places used.
Can I convert between volume (e.g., cups) and weight (e.g., grams)?
Not directly in this calculator. Volume measures space, while weight (mass) measures how heavy something is. The conversion depends on the density of the substance (e.g., a cup of flour weighs less than a cup of water). Use the 'Cooking' or 'Volume' category for volume units and the 'Mass' category for weight units.
Why are there different Gallons/Pints/Quarts?
The calculator includes both US standard units and Imperial units (used primarily in the UK and Canada). Imperial units are generally larger than their US counterparts (e.g., 1 Imperial Gallon ≈ 1.2 US Gallons). Be sure to select the correct unit system for your needs, especially in the 'Volume' and 'Cooking' categories.
What base is used for Data Storage (KB, MB, GB)?
This calculator uses base-1024 (binary prefixes: 1 KB = 1024 Bytes, 1 MB = 1024 KB, etc.), which is standard in computing contexts like operating systems. Note that some storage manufacturers market capacity using base-1000 (1 KB = 1000 Bytes), which can lead to discrepancies.

Disclaimer
While we strive to provide accurate conversion results, this tool is provided for general reference purposes only. Conversions are based on standard factors and may not account for all specific conditions or variations. Temperature conversions are based on standard formulas. Speed of sound (Mach) is approximated at standard sea level conditions (15°C, 1 atm). Data storage units (KB, MB, GB, etc.) are calculated using base-1024 (binary prefixes) as is common in computing contexts, though marketed storage often uses base-1000. Fuel consumption units (e.g., MPG) depend on the specific gallon definition (US or Imperial). Electrical units (Volt, Ampere, Ohm, Henry) assume standard DC conditions where applicable. Radiation units (Gray, Sievert) are standard SI units. For critical applications, please verify results with authoritative sources. The developers are not liable for inaccuracies or consequences resulting from its use.
