Multiple Choice

The flash point is usually expressed in which unit?

Explanation:
Flash point is the temperature at which a liquid’s vapors ignite in air. In fire hazards practice, this value is usually expressed in Celsius because most international standards and safety data sheets use the Celsius scale (SI units). This keeps data consistent across countries and materials. If you ever need Fahrenheit, you can convert, but the established convention is Celsius. Kelvin and Rankine are absolute scales used mainly in scientific calculations and aren’t the standard for reporting flash points in practical hazard information.
