79 degrees Fahrenheit = 26.11°C (299.26 K). Use the copy buttons below for any format, or enter a custom value in the converter.
Fahrenheit is the primary temperature scale in the United States, while Celsius is the international standard used by the rest of the world and all scientific disciplines. To convert Fahrenheit to Celsius, subtract 32 then multiply by 5/9: °C = (°F − 32) × 5/9. For 79°F: (79 − 32) × 5/9 = 26.11°C. Kelvin — used in science — adds 273.15 to the Celsius result: 26.11°C + 273.15 = 299.26 K.

Three practical situations where knowing that 79°F = 26.11°C makes a real difference.
Cooking techniques like sous-vide, chocolate tempering, and yogurt fermentation often reference Fahrenheit temperatures in US recipe books. 79°F equals 26.11°C — useful to know when adapting a US recipe for a metric kitchen thermometer or instant-read probe.
If you're visiting the United States and a weather app shows 79°F, that means 26.11°C. Light clothing and sunscreen are a good idea. US weather forecasts, thermostats, and ovens almost universally use Fahrenheit, so this conversion is essential for international visitors.
In physics or chemistry, temperatures are often given in Fahrenheit in US textbooks but need to be expressed in Celsius or Kelvin for formulas. 79°F = 26.11°C = 299.26 K. Kelvin is required for thermodynamic equations like the ideal gas law (PV = nRT) since it starts at absolute zero (0 K = −459.67°F). Converting 79°F: (79 − 32) × 5/9 + 273.15 = 299.26 K.
