Click the Temperature tab, enter your Celsius value in the input field, set From to Celsius and To to Fahrenheit. The formula is °F = (°C × 9/5) + 32. For quick reference: 0°C = 32°F, 20°C = 68°F, 100°C = 212°F.

Yes. All tabs support conversion between metric (SI) and imperial/US units. For length: metres to feet, kilometres to miles, centimetres to inches. For weight: kilograms to pounds, grams to ounces. For volume: litres to gallons (US or UK).

Click the Data tab, enter the value, and select GB to MB (or any other data unit pair). The converter uses binary prefixes (1 GB = 1,024 MB) for storage units, which matches how operating systems report file and drive sizes.

Yes. The calculator handles both scientific notation inputs and standard decimal values. Results for very large or small conversions are shown in standard decimal notation; for extreme values, scientific notation may appear automatically.

All conversion factors are based on exact international definitions (e.g. 1 inch = 25.4 mm exactly, 1 mile = 1,609.344 m exactly). Temperature conversions use the full formula. Results are accurate to at least 6 significant figures for all supported units.
