Subject: Support practical SI (metric) adoption in the United States

Dear Representative,

I am writing as your constituent to encourage practical, phased adoption of the International System of Units (SI) across education, manufacturing, labeling, and public communication.

The United States already uses metric in many scientific, medical, military, and industrial contexts. A clearer national strategy would reduce conversion errors, lower trade friction, and better prepare students for STEM careers in a global economy.

I support efforts that:
- Increase metric-first instruction in schools
- Encourage dual-labeling with a metric-first default
- Expand federal guidance for SI use in technical standards and procurement

Please support policies that make measurement in the US safer, simpler, and globally aligned.

Thank you for your service.

Sincerely,
[Your Name]
