Which countries still use Celsius?

Could you elaborate on which countries continue to utilize the Celsius scale for temperature measurements, despite the widespread adoption of the International System of Units (SI) which includes the Kelvin scale as its primary unit for thermodynamic temperature? Are there any particular regions or industries within these countries that maintain a preference for Celsius, and if so, what are the reasons behind this preference? Additionally, how does the continued use of Celsius in these countries compare to the global trend towards standardization and harmonization in scientific measurement?
