Engineering
Convective Heat Transfer Calculator
Calculate convective heat transfer rate from a solid surface to a flowing fluid (or vice versa) using Newton's law of cooling. Use it to size heat exchangers, evaluate HVAC equipment, or estimate building heat loss.

Engineering
Thermal Expansion Calculator
Calculates how much a material elongates when its temperature changes, using the linear thermal expansion formula. Use it when designing pipework, rail joints, bridge expansion gaps, or any structure subject to temperature fluctuations.
