Refactor LengthConversions and WeightConversions classes for improved code style

- Updated class definitions to follow PSR standards by adding opening braces on the same line.
- Adjusted method definitions to align with coding conventions.
- Ensured consistent formatting and spacing throughout the conversion methods.
