Translate technical requirements between international standards and regional unit systems for field engineering project specs.

Verify technical data sheets, equipment specifications, and safety audit reports against standard unit guidelines.

Common Mistakes to Avoid

Using Math.random() instead of crypto.getRandomValues()

Math.random() is not cryptographically secure and may produce predictable sequences. Always use crypto.getRandomValues() (browser) or crypto.randomUUID() for UUID generation.

Assuming UUIDs are sequential or sortable

UUID v4 is purely random with no ordering guarantee. If you need time-sortable IDs, use UUID v7 (timestamp + random) or ULID instead.
