The second. Also, several units used with electricity: Volt, Watt, Ohm, and others.
The unit of mass, the kilogram, is a part of both the US customary system and the metric system. In the US customary system, pounds are used for mass measurement, while the metric system uses kilograms.
The measurement kHz (kilohertz) is a unit of frequency commonly used in electronics and telecommunications. It is part of the International System of Units (SI) and is not specific to either the English or Metric system.
The United States is one of the few countries that officially uses both the metric and customary system of measurement. Myanmar uses a combination of both systems as well.
The teaspoon measurement is commonly used in both the metric and English systems. In the metric system, a teaspoon is equivalent to 5 milliliters, while in the English system it is equal to about 4.9 milliliters.
The unit that belongs to both the US and metric system is the meter (m) for length measurement.
They are both systems of measurement except that the metric system is simpler and used by the majority of the world.
The SI system. (Metric, base ten)

Both imperial and metric is currently used in the UK. The metric system is exclusively taught in UK schools. So, eventually, as children become adults, the metric system will become the norm. Resistance to using the metric system is usually from adults who were taught the imperial system when they were schoolchildren.
The unit that belongs to both the US and metric system is the meter (m) for length measurement.
Those two nations are both Liberia, Myanmar, and the USA.
For just about any type of unit, different units are used between the English system and the SI (metric) system. In both systems, there are units for length, area, volume, mass, force, temperature, etc.
The unit of time ... the 'second' ... is the same in both systems of measurement.
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.
