Converters

Converters translate one representation into another: metric to imperial, one currency to the next, timestamps to readable dates, or a file from one format to a format your software will accept. They solve small problems that appear constantly and are rarely worth dedicated software.

Two things separate a good converter from a frustrating one. The first is where the work happens; tools that convert in the browser never upload your file, which matters for anything confidential. The second is freshness, since currency and exchange-rate converters are only as accurate as the feed behind them, so check when the rates were last updated.
