Frequently Asked Questions

  • QHow do I convert Celsius to Fahrenheit?
    Multiply Celsius by 9/5 and add 32. Formula: °F = (°C × 9/5) + 32. For example, 20°C equals 68°F.
  • QWhat is the SI unit of temperature?
    The SI base unit for temperature is kelvin (K), where absolute zero is 0 K (-273.15°C).
  • QWhat is absolute zero?
    Absolute zero is 0 K (-273.15°C or -459.67°F), the lowest theoretically possible temperature where all thermal motion ceases.
