Converter - for general use

Story

Convert any value in seconds into a relevant unit of time, from nanoseconds to millenia.

Avoid over-precision ie show 1.5 hours, not 1.504 hours. Prefer "Just over 1.5 hours"

Use plurals i.e. 5 seconds, not 5 second

Example output

1 second is 1 second

0.009 seconds is 9 microseconds

3601 seconds is just over 1 hour

Sources for Time Units

• Units of time from wikipedia, and a handy table of cross-references.
• General conversion from DuckDuckGo

Fixes

Algorithm: better handling of negative and zero values

Testing: Added two tests to verify changes

Testing: Bulk data generation avoids numeric problems (i.e. step of 0.001 no longer occasionally produces x.xx0000000000000001)

Testing: Deeper info on metric units: sources and configuration used

Known Issues

• 001: 0.7 seconds is just under 700 microseconds
