How it's used
Scientific usage in Hong Kong follows the SI prefix convention where it represents one million. This is distinct from the traditional Chinese numerical system where it can represent much larger values like one trillion or even higher depending on the historical context. In modern technical contexts, it is almost exclusively used as a prefix for units of measurement.
Examples
What is the processor speed of this computer in megahertz?

Common mistake
Avoid using this to mean a trillion in modern scientific or technical discussions, as it will cause confusion with the SI prefix meaning of one million. Stick to standard numerical terms like 萬億 for larger values to ensure clarity.
