Tips
- Use the
list command to see all available units for a category
- Temperature units are case-sensitive (C, F, K)
- For compound units like m/s, use the slash notation
- The converter handles both short and long unit names
- Results are formatted for readability
Troubleshooting
"Cannot convert" error:
- Check unit spelling
- Ensure units are from the same category (e.g., don't convert length to weight)
- Use
list command to see available units
Unexpected results:
- Temperature conversions use standard formulas
- Data conversions use 1024-based (binary) units
- Double-check unit case sensitivity
Notes
- Temperature conversions use standard formulas
- Data conversions use binary (1024-based) units
- All other conversions use decimal (1000-based) units
- Results are automatically formatted for readability
