What units of data storage are supported?: FileFlip supports bit, byte, kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), and petabyte (PB). Conversions use the decimal system (1 KB = 1000 bytes) standard in storage marketing, not the binary system (1 KiB = 1024 bytes) used in operating systems.
Can I convert cooking measurements?: Yes. The Volume category includes teaspoon, tablespoon, fluid ounce, cup, pint, quart, and gallon alongside metric units (ml, cl, dl, L). This covers all common cooking and baking measurements used in both US and European recipes.
How accurate are the conversions?: Conversions use precise scientific conversion factors and display up to 6 significant decimal places. For everyday use the results are exact. For highly specialized scientific or engineering calculations, we recommend using the displayed formula to verify precision requirements.
Can I convert nautical miles and knots?: Yes. Nautical miles are available in the Length category and knots (nautical miles per hour) are included in the Speed category. These are particularly useful for navigation, aviation, and maritime applications.
Is there a way to see multiple conversions at once?: Yes. Below the main result, FileFlip shows a quick reference table with the most common equivalent values for your input. For example, entering 1 kilometer shows the equivalent in meters, centimeters, miles, feet, yards and inches simultaneously.
Does the unit converter work offline?: Once the page is loaded, all conversions work without an internet connection since they are pure mathematical calculations done in your browser. However, you need to be online to initially load the page.
