What is the standard unit for temperature?

• A. Degrees Celsius
• B. Meters
• C. Liters
• D. Kilograms

Answer: (A)

Temperature is measured on scales that assign numbers to how hot or cold something is. Degrees Celsius is commonly used as the standard unit in many chemistry contexts because it aligns with water’s familiar phase changes: 0 degrees is the freezing point and 100 degrees is the boiling point at standard pressure. This makes it intuitive and easy to read from thermometers and to relate to everyday experiences and lab results. Although the strict SI unit for temperature is kelvin, degrees Celsius remains the typical standard in many educational and practical settings, and you can convert between them by adding or subtracting 273.15. The other options measure different quantities—meters for length, liters for volume, and kilograms for mass—so they’re not used to express temperature.
