Understanding Temperature Conversions
Temperature scales serve different purposes: Celsius for everyday use in most countries, Fahrenheit in the US for weather, and Kelvin for scientific applications. Each has its own reference points.
💡 Room temperature: 20-22°C = 68-72°F = 293-295K
Frequently Asked Questions
Why does the US still use Fahrenheit?
The US adopted Fahrenheit before the metric system became widespread. Fahrenheit offers finer granularity for weather (0-100°F roughly covers typical US weather), and changing would require massive infrastructure updates to weather forecasts, thermostats, and medical standards.
What is absolute zero and why does it matter?
Absolute zero (0 Kelvin, -273.15°C, -459.67°F) is the lowest theoretically possible temperature where molecular motion stops. It's a fundamental physical limit used in scientific calculations and is why Kelvin has no negative values.
How do I convert cooking temperatures?
Multiply Celsius by 1.8 and add 32 to get Fahrenheit. Common oven temperatures: 180°C = 356°F (moderate), 200°C = 392°F (hot), 220°C = 428°F (very hot). For fan ovens, reduce by about 20°C from conventional settings.
What temperature scales are used in science?
Kelvin is the SI standard for scientific work as it starts at absolute zero. Celsius is also widely used in chemistry and biology. Rankine (Fahrenheit-based absolute scale) is occasionally used in some US engineering applications.
At what temperature are Celsius and Fahrenheit equal?
-40 degrees is the same in both Celsius and Fahrenheit. This is a useful memory trick: -40°C = -40°F exactly. Above this point, Fahrenheit values are higher; below, they're lower (more negative).
