Explanation / Answer

Please find the answers below:

Answer 9: The metric units of measurement are the standard forms such as meter for length, kilogram for weight, litre for volume, hour for time etc.

Answer 10: The relationship between different units is:

1cm = 1000 mm and 1cm= 10-5m

Thus, the conversions can be performed for a 25 mm pencil as:

25*10-3 cm and 25*10-5 m
