✓Quick mental conversion: °C × 2 + 30 ≈ °F (close enough for weather).

✓Exact formula: °F = (°C × 9/5) + 32 and °C = (°F − 32) × 5/9.

✓Kelvin is used in science — it's the same scale as Celsius, just shifted by 273.15.

✓Normal fridge temperature: 0–4°C (32–39°F). Freezer: -18°C (0°F).

How do I convert Celsius to Fahrenheit?+

Multiply by 9/5 (or 1.8) and add 32. Example: 25°C × 1.8 + 32 = 77°F.

What temperature is the same in both Celsius and Fahrenheit?+

-40° is the same in both Celsius and Fahrenheit. This is where the two scales intersect.

What is absolute zero?+

0 Kelvin = -273.15°C = -459.67°F. It is the theoretical lowest possible temperature where all atomic motion stops.
