The correct way of writingh the SI units?

The correct way of writing SI units includes using uppercase letters for units named after people (e.g., Newton, Joule) and lowercase letters for all other units (e.g., meter, gram). Unit symbols should be written in singular form, regardless of quantity (e.g., "m" for meters, not "ms" for meters). Additionally, there should be a space between the numerical value and the unit symbol (e.g., "5 m"), except for degree symbols (e.g., "30 °C"). Finally, unit symbols should not be pluralized (e.g., "2 m," not "2 ms").
