How do you convert Celsius to Fahrenheit?

Multiply Celsius by 1.8 and add 32: `°F = (°C × 1.8) + 32`. For example, 100°C boiling point is `(100 × 1.8) + 32 = 212°F`.

How do you convert Fahrenheit to Celsius?

Subtract 32 from Fahrenheit, then divide by 1.8: `°C = (°F - 32) / 1.8`. For example, 32°F freezing point is `(32 - 32) / 1.8 = 0°C`.

How do you convert Celsius to Kelvin?

Add 273.15 to the Celsius temperature: `K = °C + 273.15`. Absolute zero is 0 K or -273.15°C.

At what temperature are Celsius and Fahrenheit equal?

Celsius and Fahrenheit are exactly equal at -40 degrees (-40°C = -40°F).

What is normal human body temperature across scales?

Normal human body temperature averages 37°C, 98.6°F, or 310.15 K.

What is Absolute Zero in Kelvin, Celsius, and Fahrenheit?

Absolute zero equals 0 Kelvin, -273.15° Celsius, and -459.67° Fahrenheit.

What Is the Formula to Convert Celsius to Fahrenheit?

The formula to convert Celsius (°C) to Fahrenheit (°F) is: °F = (°C × 9/5) + 32 (or °F = °C × 1.8 + 32). For example, 20°C converts to (20 × 1.8) + 32 = 68°F. To convert Fahrenheit back to Celsius: °C = (°F - 32) × 5/9.

Mathematical Formula & Equations

Converts temperature measurements across Fahrenheit ($^\circ\text{F}$), Celsius ($^\circ\text{C}$), and Kelvin (K).

\[ F = (C \times \frac{9}{5}) + 32, \quad C = (F - 32) \times \frac{5}{9}, \quad K = C + 273.15 \]

Calculation Example

Human body temperature $37^\circ\text{C} = (37 \times 1.8) + 32 = 98.6^\circ\text{F} = 310.15\text{ K}$.
