Estimation and education only
BTU to Watts (the “Site”) provides power-unit conversion tools and educational content. Every result is intended for estimation, comparison, and learning. Nothing on the Site is a substitute for professional engineering judgment, code-compliant design documents, or manufacturer specifications.
No professional advice
The content and calculators do not constitute professional engineering, electrical, mechanical, HVAC, financial, or legal advice. Always consult a licensed professional before making decisions that affect safety, code compliance, or significant expense.
Accuracy limits
We use the standardized factor 1 BTU/hr = 0.29307107 W and related SI-derived ratios, and we take care to display accurate numbers. Even so, we do not warrant that every value shown is free of error. Rounding, browser floating-point behavior, and equipment-specific assumptions can introduce small differences.
Before you rely on a result
- Verify critical numbers with a second source or a licensed professional.
- Cross-check against manufacturer specifications for the actual equipment.
- Account for real-world factors — insulation, climate, ductwork, and load — that a general calculator cannot know.
Limitation of liability
To the fullest extent permitted by law, the Site and its operators are not liable for any direct, indirect, incidental, consequential, or punitive damages arising from your use of the Site — including incorrect sizing decisions, equipment failures, construction errors, or lost profits. Your sole remedy for dissatisfaction with the Site is to stop using it.
External links
The Site may link to third-party pages for reference. We are not responsible for the content, accuracy, or practices of any external site.
