Temperature Converter — Convert Between All Temperature Scales
Temperature conversion is one of the most frequently needed unit conversions in everyday life — from weather forecasts to cooking recipes, scientific research to medical readings. Our Temperature Converter handles all four major temperature scales with instant, precise results.
Supported Temperature Scales
Celsius (°C) — The standard scientific and everyday scale in most of the world. Water freezes at 0°C and boils at 100°C.
Fahrenheit (°F) — Used primarily in the United States for weather, cooking, and everyday temperature references. Water freezes at 32°F and boils at 212°F.
Kelvin (K) — The absolute temperature scale used in science and physics. 0 K (absolute zero) is the coldest possible temperature (-273.15°C). No degree symbol is used.
Rankine (°R) — The absolute temperature scale based on Fahrenheit increments. Used primarily in engineering applications in the United States.
Conversion Formulas
- °C to °F: (°C × 9/5) + 32
- °F to °C: (°F - 32) × 5/9
- °C to K: °C + 273.15
- K to °C: K - 273.15
- °F to K: (°F + 459.67) × 5/9
Common Reference Temperatures
| Description | °C | °F | K | |---|---|---|---| | Absolute zero | -273.15 | -459.67 | 0 | | Water freezes | 0 | 32 | 273.15 | | Room temperature | 20–22 | 68–72 | 293–295 | | Body temperature | 37 | 98.6 | 310.15 | | Water boils | 100 | 212 | 373.15 |
Practical Applications
Cooking: Recipes from different countries use different scales. US recipes use °F; most others use °C. Convert oven temperatures precisely.
Weather: When traveling between countries with different weather reporting conventions, convert forecasts instantly.
Science and engineering: Kelvin is essential in thermodynamics, chemistry, and physics calculations.
Medical: Convert patient temperature readings between Celsius and Fahrenheit for international medical records.
