About the Temperature Converter
Temperature conversions between Celsius (the global scientific and most country standard) and Fahrenheit (USA and some informal contexts) come up frequently in cooking, weather discussions, scientific work, and medical contexts. Kelvin is used in science and engineering. The conversion formulas are simple but easy to mix up under pressure - this converter handles all three scales instantly.
Temperature Conversion Formulas
°F = (°C × 9/5) + 32 · °C = (°F - 32) × 5/9 · K = °C + 273.15
Water freezes: 0°C = 32°F = 273.15 K · Water boils: 100°C = 212°F = 373.15 K · Body temperature: 37°C = 98.6°F · Room temperature: 22°C = 71.6°F · Oven temp 180°C = 356°F
Worked Example
Recipe requires baking at 350°F - set oven in Celsius
°C = (350 - 32) × 5/9 = 176.7°C · Round to 175°C or 180°C for oven setting
Tips & Insights
- 1
A quick rough conversion: °F to °C = subtract 30, divide by 2. Not exact but good for weather estimates (68°F: (68-30)/2 = 19°C - actual is 20°C).
- 2
Medical thermometers in India use Celsius; some imported ones show Fahrenheit. Fever (>37.5°C = >99.5°F) threshold is consistent across both.
- 3
Oven temperatures on foreign recipe cards are almost always in Fahrenheit - always convert for Indian ovens calibrated in Celsius.
Why this matters for you
Temperature unit confusion causes real mistakes: a recipe baked at 350°C instead of 350°F burns completely (350°C = 662°F - nearly twice as hot). Medical temperature misinterpretation can delay treatment. For cooking, construction (concrete curing temperatures), and HVAC specifications, accurate temperature conversion is a practical daily necessity.
