How to Use This Converter
Enter a temperature value, select your starting unit (Celsius, Fahrenheit, or Kelvin), and all three values are shown instantly. Celsius is used in Nigeria for weather, cooking, and medicine. Fahrenheit appears in older appliance manuals and American recipes.
The Formulas
Celsius to Fahrenheit: °F = (°C × 9/5) + 32
Fahrenheit to Celsius: °C = (°F − 32) × 5/9
Celsius to Kelvin: K = °C + 273.15
Kelvin to Celsius: °C = K − 273.15

FAQ
Normal body temperature is 36.5–37.5°C (97.7–99.5°F). A temperature above 38°C (100.4°F) is classified as a fever by Nigerian hospitals and the WHO. For children, a temperature above 38°C warrants medical attention, especially given the risk of malaria in Nigeria. Axillary (armpit) temperatures read about 0.5°C lower than oral temperatures.
Kelvin is the SI base unit of temperature used in physics and chemistry because it starts at absolute zero (−273.15°C) — the coldest theoretically possible temperature. This makes calculations involving energy, gas laws, and thermodynamics simpler. In everyday Nigerian life, Celsius is standard for all practical purposes.
Nigerian gas and electric ovens typically range from 120°C (250°F) for slow cooking to 250°C (480°F) for high heat. For baking Nigerian chin-chin: 180°C (350°F). For bread: 200–220°C (390–430°F). Many older Nigerian ovens use Fahrenheit markings on the dial, which is where this converter is useful. Gas marks 1–9 correspond to approximately 140–240°C.
