Ideal for scientists, engineers, and travelers switching between U.S. and metric temperature standards.
How to Use This Calculator
Enter Fahrenheit
Type the temperature in °F from your source (weather report, thermostat, sensor log).
Review conversions
Celsius, Kelvin, and Rankine equivalents appear instantly for easy comparison.
Apply the results
Use the converted values in recipes, lab notes, or configuration files expecting other scales.
Formula
°C = (°F − 32) × 5/9
K = (°F − 32) × 5/9 + 273.15
°R = °F + 459.67
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Fahrenheit remains the standard in the United States, but science and most of the world rely on Celsius and Kelvin. This converter bridges the gap so you can interpret and share data without miscommunication.
Kelvin and Rankine are absolute temperature scales (starting at absolute zero), which makes them essential for thermodynamics and physics.
The formulas follow SI definitions and handle fractional temperatures to support lab-grade accuracy.
Frequently Asked Questions
Can it handle sub-zero temperatures?
Yes. Negative Fahrenheit values convert correctly to the other scales.
Is Rankine still used?
Rankine appears in certain engineering fields, especially those using imperial units. This converter keeps it available alongside Kelvin.
Does it support decimals?
Absolutely. Enter decimal temperatures for precise readings.
How do I convert back to Fahrenheit?
Use °F = (°C × 9/5) + 32, or rely on the Fahrenheit-to-Celsius tool for direct conversions.
