Conversions use the exact definitions, such as 1 inch = 2.54 centimetres and 1 pound = 0.45359237 kilograms, and results are rounded only for display.

Choose the Temperature category, enter the value, and pick Celsius as the from unit and Fahrenheit as the to unit. The formula is Fahrenheit = Celsius x 9/5 + 32.

Decimal units (kilobyte, megabyte) use 1000, and binary units (kibibyte, mebibyte) use 1024, so both conventions are available.
