Frequently Asked Questions
01 How accurate are the conversions?
All conversions use standard scientific conversion factors with full floating-point precision. The results are accurate to at least 10 decimal places, matching or exceeding the precision of most scientific calculators.
02 Is my data sent to a server?
No. All conversions happen entirely in your browser using JavaScript. Tools Oasis never sends, stores, or logs any values you enter.
03 How does temperature conversion work?
Temperature conversion uses the standard formulas: Celsius to Fahrenheit is (C x 9/5) + 32, Celsius to Kelvin is C + 273.15, and so on. Unlike other unit types, temperature conversions are not simple multiplication — they involve offsets.
04 What is the difference between metric and imperial units?
Metric units (meters, kilograms, liters) are based on powers of 10 and used worldwide. Imperial units (feet, pounds, gallons) are primarily used in the United States, Liberia, and Myanmar. This converter handles both systems seamlessly.
05 Can I convert data storage units?
Yes. The Data/Storage tab lets you convert between Bytes, Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB). All conversions use the binary standard (1 KB = 1024 Bytes).
