Instantly convert between Celsius, Fahrenheit, Kelvin and other temperature units with our accurate tool
Convert between different temperature units with precision
Temperature conversion is essential in science, cooking, engineering, and daily life when dealing with different measurement systems. Our free Temperature Converter allows you to instantly switch between Celsius, Fahrenheit, Kelvin, and other temperature scales with precision.
Standard in most of the world
Common in the United States
Scientific and SI unit of temperature
Absolute temperature scale based on Fahrenheit
0°C → 32°F
°F = (0 × 9/5) + 32 = 32
100°C → 212°F
°F = (100 × 9/5) + 32 = 212
0°C → 273.15K
K = 0 + 273.15 = 273.15
32°F → 273.15K
K = (32 - 32) × 5/9 + 273.15 = 273.15
✅ Accurate calculations - Based on scientific formulas

Ideal for students, teachers, scientists, chefs, travelers, and anyone who needs to work with temperature measurements.
Temperature is the conversion everyone meets abroad: a forecast in Fahrenheit, an oven setting in Celsius, a science problem in Kelvin. This converter switches between Celsius, Fahrenheit, Kelvin and Rankine with scientific accuracy, updating in real time as you type. Unlike a bare calculator, it shows the working — the actual formulas and stepped examples (0°C = 32°F; 100°C = 212°F; 0°C = 273.15 K) — so students can learn the method and anyone can double-check a result before trusting it.
It covers daily life (weather and travel), the kitchen (recipes and oven settings), and study and lab work where Kelvin and Rankine appear. Clean, responsive and private. Free, with no sign-up.
Celsius, Fahrenheit, Kelvin and Rankine.
°F = (°C × 9/5) + 32 — so 100°C = 212°F. The page shows the stepped calculation for common conversions.
Kelvin is the scientific (SI) unit of temperature, common in physics, chemistry and engineering.
Yes — no sign-up required, and conversions happen in real time as you type.
