About Temperature Conversion

Temperature conversion is crucial in scientific research, engineering applications, cooking, and daily weather reporting. Different regions use different scales: Celsius (metric system), Fahrenheit (US customary), Kelvin (SI base unit), and Rankine (engineering).

Conversion Formulas

Celsius to Fahrenheit: °F = (°C × 9/5) + 32
Fahrenheit to Celsius: °C = (°F - 32) × 5/9
Celsius to Kelvin: K = °C + 273.15
Kelvin to Celsius: °C = K - 273.15
Fahrenheit to Rankine: °R = °F + 459.67
Rankine to Fahrenheit: °F = °R - 459.67

Practical Examples

Weather: Convert 25°C to Fahrenheit for international weather reports
Cooking: Convert 180°C to Fahrenheit for oven settings
Science: Convert 298K to Celsius for chemical experiments

Reference Table

Scale	Freezing Point	Boiling Point	Absolute Zero
Celsius (°C)	0	100	-273.15
Fahrenheit (°F)	32	212	-459.67
Kelvin (K)	273.15	373.15	0
Rankine (°R)	491.67	671.67	0

Important Notes

Kelvin and Rankine are absolute scales starting at absolute zero
Some conversions involve offsets as well as ratios
Significant figures should be maintained in scientific calculations
