Calculations and Conversions
KRunner includes a calculator that not only does basic arithmetic, but also advanced mathematical functions [2], including algebra, calculus, and geometry. In addition, typing a figure followed by a standard currency abbreviation (i.e., $ or §) or a three letter abbreviation (i.e., CAD for Canadian Dollars or GBP for Great British Pound) will show its current exchange rate with other currencies based on figures from the European Central Bank. In the same way, you can enter measurements with standard abbreviations such as lb for pound and k for kilometer to convert them into other units – a function especially useful for those who switch regularly between metric and imperial systems.
Finding Date and Time
Entering date or time displays current information. By default, the results are for your system's time zone, but another time zone can be added at the end of the command. For some reason, the results are in a formal sentence, and there is no way to change the format, which somewhat lessens the usefulness.
Spelling and Special Characters
The command spell STRING suggests possible alternative words, while #HEXADECIMAL UNICODE shows a special character. In both cases, selecting a result copies it to the clipboard so you can paste it into a document.
