- "How fast is 100 km/h in mph?"
- "Convert 10 kg to pounds"

Args:
    value: The numeric value to convert
    from_unit: Source unit (e.g., 'mph', 'kg', 'J')
    to_unit: Target unit (e.g., 'm/s', 'lb', 'kWh')

Returns:
    Dictionary with:
    - original_value: Input value
    - original_unit: Input unit
    - converted_value: Result value
    - converted_unit: Result unit
    - formatted: Human-readable string

Examples:
    >>> convert_unit(100, 'm/s', 'mph')
    {
        "original_value": 100,
        "original_unit": "m/s",
        "converted_value": 223.694,
        "converted_unit": "mph",
        "formatted": "100 m/s = 223.694 mph"
    }

    >>> convert_unit(60, 'mph', 'km/h')
    {
        "original_value": 60,
        "original_unit": "mph",
        "converted_value": 96.56064,
        "converted_unit": "km/h",
        "formatted": "60 mph = 96.56 km/h"
    }
