FAQ
Is this converter accurate for engineering calculations?
Yes, all conversion factors are based on internationally accepted standards. Results are displayed with high precision suitable for preliminary engineering estimates.
Does this converter work offline?
Yes! The converter is entirely client-side JavaScript. Once the page loads, no internet connection is needed for conversions.
What is the most common conversion in HVAC work?
BTU/h to kW (power) and CFM to m³/h (air flow) are among the most frequent conversions, especially when working between ASHRAE and international standards.
Is there an API for programmatic access?
Yes, a REST API endpoint is available at POST /api/v1/calculators/converter for server-side integration.
