Tips to avoid mistakes
- Round smart: For estimates, round to 2 decimals. For forms, use the level of precision the page requests.
- Use consistent units: If a store lists dimensions in cm, convert all dimensions (L/W/H) to inches (or vice versa) together.
- Don’t guess weights: For faster clearance and fewer delays, keep proof of purchase ready (see invoices & proof of purchase).

FAQs
Boxit4me pages and carriers may display weights and dimensions in different units depending on the route and carrier. If you’re unsure, convert values here and double-check in the shipping calculator.
The cost itself doesn’t change, only the unit format. Differences usually come from rounding or using inconsistent units (e.g., converting weight but not dimensions).
Often yes, many customs and carrier systems accept both, but accuracy matters. Use this guide and review the customs declaration steps for clean item descriptions.
