Metric is an adjective and refers to a system of measurement.
Metric measurement is measurement made using units as defined under the metric system.
Mass
The only element of time defined in the metric system is the second. Which is defined as 'a certain number of ... ... .' [Never mind the recipe.] You may still use days, hours, minutes and so on in the metric system.
There are no sports listed. However, most sports are now defined in terms of metric measures. Furthermore, athletes' performance is also measured using metric units.
Matter is defined as that which has mass and occupies space. There are procedures to measure both. Even if you can't measure the mass of an object directly (such as a gas), you can still determine it's mass by measuring the space it occupies. Pressure is one way to measure the mass of gas by the amount of space it occupies.
the meter is defined as the basic unit of the metric unit.

It is exactly one teaspoon. One standard US teaspoon is defined as 4.929ml. In the UK it is defined as 4.736 mL, and a metric teaspoon is defined as 5ml exactly.
It is well-defined, consistent and more practical.
"Magnitude" is the size or distance. Its measure depends on the metric that is defined on the relevant space.
