138 degrees Fahrenheit = 58.89°C (332.04 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 138°F: (138 − 32) × 5/9 = 58.89°C. Kelvin — used in science — adds 273.15 to the Celsius result: 58.89°C + 273.15 = 332.04 K.

Three practical situations where knowing that 138°F = 58.89°C makes a real difference.
Cooking techniques like sous-vide, chocolate tempering, and yogurt fermentation often reference Fahrenheit temperatures in US recipe books. 138°F equals 58.89°C — useful to know when adapting a US recipe for a metric kitchen thermometer or instant-read probe.
138°F (58.89°C) is outside the range of typical daily weather. You'd encounter this in extreme climate science, industrial contexts, or laboratory settings.
In physics or chemistry, temperatures are often given in Fahrenheit in US textbooks but need to be expressed in Celsius or Kelvin for formulas. 138°F = 58.89°C = 332.04 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 138°F: (138 − 32) × 5/9 + 273.15 = 332.04 K.
