Unit Converter

Convert between different measurement units. Supports length, weight, temperature, area, volume, speed, time, and data units.

When to Use

• Convert between metric and imperial units
• Calculate unit equivalencies
• Work with different measurement systems
• Convert digital storage sizes

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
