"Utilisation" and "utilization" are the same in meaning, referring to the act of using something effectively, differing only in British (utilisation) and American (utilization) spelling.

Key Differences

"Utilisation" is the British English spelling of the term, reflecting the typical British use of 's' in such words. "Utilization," on the other hand, follows the American English convention of using 'z', a common difference in spelling between these English forms.
In terms of pronunciation, "utilisation" and "utilization" sound almost identical, with a slight variation in the 's' and 'z' sounds, reflecting their respective British and American pronunciations.
Both "utilisation" and "utilization" convey the process of making effective use of something, without any difference in their meanings or contexts where they can be applied.
In academic and professional writing, "utilisation" is preferred in British English contexts, while "utilization" is more common in American English publications, adhering to the respective spelling norms.
Despite their spelling differences, "utilisation" and "utilization" are interchangeable in global English, with the choice of usage depending largely on the geographical or cultural preference of the writer or audience.
