It makes it easier to get a sense of scale and understanding. For example what is easier to see?
An apple weighing 100g OR
An apple weighing 0.0001 tonnes

Another contributor followed up on the same idea:
If you only had one unit for measuring, then you'd often wind up with
inconvenient numbers that were hard to handle or remember.
Examples:
If we only had millimeters, then grandma might live 35000000 of them away.
If we only had kilometers, then a wave of light might be 0.0000000004 of them long.
If we only had microseconds, then I would be 2208911040000000 of them old,
and the number would be changing too fast to read it.
It is a measuring tape which is calibrated in metric units.
That depends what you are measuring. There are lots of different units to measure different things: length, area, volume, weight, mass, force, etc.
They didn't. Metric Units were developed independently of Imperial units. Originally each country, and sometimes different parts of the same country, had different sets of units. The Metric System was invented to solve the confusion of different units used in different parts of France. Gradually other countries adopted Metric and abolished their own units. The British Imperial units were one of the last to be abolished.
There are thousands of different units for measuring hundreds of different attributes. The question needs to be a bit more specific.There are thousands of different units for measuring hundreds of different attributes.

They are both systems of measurement in which there are sets of 7 units for measuring physical attributes of objects and derived units for measuring other attributes. For example, Basic units for mass: Kilogram (metric) or Pound (Imperial) Derived units for area: Square Metre (metric) or square inch (Imperial) Derived unit for pressure: kg / sq metre = Pascal (metric) or pounds / square inch = psi (Imperial).

A metric ruler is a measuring tool used to measure lengths in metric units such as millimeters, centimeters, and meters. It helps provide accurate measurements for objects or distances in a standardized way.
The metric unit for measuring time on a stopwatch is seconds.
How about fractions of a millimetre?

Common units for measuring volume in the metric system are milliliters (mL) and liters (L). The tool commonly used for measuring liquid volumes in the metric system is a graduated cylinder.
Units with divisions that are powers of ten are called metric units. This system of measurement makes it easier to convert between different units by simply moving the decimal point. Examples include meters, grams, and liters.
