Use Newton's law of cooling to solve convection heat rate, heat-transfer coefficient, area, or temperature difference.
Convection heat-transfer rate
2500 W
Unit-normalization summary: SI base units; heat-rate
Qdot = h A deltaT
Qdot = h A deltaT
Positive heat transfer follows the stated hot-to-cold or heat-added sign convention.
Convection is heat transfer between a surface and a moving fluid, represented in simple calculations by Newton's law of cooling. Heat-transfer coefficient, exposed area, and surface-to-fluid temperature difference determine the idealized heat rate; the coefficient itself depends on flow and geometry.
Convection Calculator applies this concept to its defined inputs and workflow. This convection calculator uses q = h A delta T with explicit unit normalization and does not estimate h from Nusselt-number correlations. Its governing relationship or workflow is stated as follows: Convection heat transfer from user-entered heat-transfer coefficient, area, and temperature difference.
The calculator evaluates Calculation mode, Temperature difference, and Display precision and returns Convection, base-unit normalization, formula substitution, and calculation steps using the stated method. The selected units and sign or reference conventions must describe one consistent physical case. Users should interpret the output within the assumptions shown on the page and repeat the check with trusted reference values when the result affects engineering or research decisions. Thermal properties are treated as constant user-entered values.
| Symbol | Meaning | Unit |
|---|---|---|
| h | Convection heat-transfer coefficient | W/(m2 K) |
| A | Convection area | m2 |
| delta T | Surface-to-fluid temperature difference | K |

This tool is intended for educational, estimation, and preliminary engineering use. Always verify critical heat-transfer calculations with applicable standards, validated software, measured properties, and qualified professional judgment before using results in real design, manufacturing, construction, safety, or compliance decisions.
