Educational calculations

Thermal models simplify real systems. Material properties can vary with temperature, pressure, composition, moisture, density, ageing and manufacturing method. Boundary conditions, geometry, contact resistance, thermal bridges, transient behaviour and measurement uncertainty can also change actual results.

Use the calculators to learn, explore relationships and perform preliminary checks. Do not treat a calculated result as a measured value or as proof that a design complies with a standard.

Engineering and building decisions

The site does not provide professional engineering services. Building heat-loss estimates do not replace formal HVAC load calculations, code-compliance procedures, site inspection or equipment-selection work. Electronics thermal estimates do not replace component datasheets, validated thermal simulations or testing under actual mounting and airflow conditions.

Health and workplace heat

Human thermal-comfort and environmental-heat information is educational. It does not diagnose illness, determine medical fitness, prescribe treatment or establish that a person or workplace is safe. Heat stress depends on environmental conditions, workload, clothing, acclimatisation, health and other factors. For workplace heat hazards, follow applicable regulations and authoritative occupational-safety guidance.

Food and cooking information

Cooking and food-heating tools explain physical relationships such as boiling point, conduction, convection, evaporation and phase change. They do not determine whether food is microbiologically safe, pasteurised or ready to eat. Use current food-safety guidance for minimum temperatures, holding times, cooling, storage and other safety decisions.

Heat perception and pungency

Pages about chilli heat, Scoville ratings, thermal sensation and contact temperature describe chemical, sensory and heat-transfer mechanisms. They do not predict an individual person's pain response, injury threshold or medical reaction. Sensitivity varies between people and conditions.

Reference data

Representative property values are labelled with conditions or limitations where practical. For professional decisions, use current data from the manufacturer, applicable standard, recognised reference source or laboratory measurement that matches the actual material and operating state.

No warranty of a particular outcome

The site aims for factual accuracy and correct implementation, but no website can guarantee that every input, assumption or model matches a particular real-world situation. You remain responsible for deciding whether a tool is suitable for your intended use.
