General information only
Everything on Crown Calculator is provided for general information and education. Results come from standard formulas and are rounded for display, usually to two decimal places. Check important figures independently.
Health and body temperature
Some pages describe body temperatures, such as normal ranges and fever thresholds. These are general reference points drawn from public health sources, which are cited on each page. They are not medical advice and cannot tell you whether you or someone else is unwell. Normal body temperature varies between people and through the day.
If a temperature reading or symptom worries you, contact a doctor, pharmacist or your local health service. In an emergency, call your local emergency number.
Cooking and food safety
Oven conversions show the exact equivalent temperature. Recipes often round these (for example 180°C to 350°F), and ovens vary, so follow your recipe and your oven's guidance. For food safety, use the official guidance for your country on safe cooking and holding temperatures.
Scientific and technical use
Conversions use the defining formulas for the Celsius, Fahrenheit and Kelvin scales. For laboratory, engineering or regulatory work, confirm values against the standard your work requires.
No warranty
Results are provided without warranty of any kind. The terms of use set out the limits of liability.
