No.
Inches, feet, miles, and pounds are some units that are not part of the SI.
No, not all metric units are part of the International System of Units (SI). The SI is a coherent system of units derived from the metric system, but it is more specific and defined, and not all metric units are included in the SI.
No, pounds and inches are not part of the SI (International System of Units). The SI system uses kilograms for mass and meters for length.
in america, the units on a measuring cup are part of a system called SI, or the international system of units
Yes, the kilogram is a unit of mass in the metric system. It is the base unit for mass in the International System of Units (SI).
Meters
I don't know exactly what you mean; but neither ounces nor gallons are part of the metric system. Look at the Wikipedia article on "SI" to get information about the current, official, version of the metric system.
Possible units for measuring mass in the metric system include grams (g), kilograms (kg), and milligrams (mg). Other units like metric tons (t) can also be used for larger masses. These units are part of the International System of Units (SI) and are commonly used in scientific and everyday contexts.
Centimeters are part of the SI unit, or international system of units. Scientists all over the world use this system of measurement, and is the only system of measurement that every scientist in the world uses.
Kg (kilogram) is the standard - although it is not a standard of weight, but of mass. The kilogram is used world-wide as the standard of mass. It is part of the SI (the International System of units).
A cubit Yeah, that is a unit that is not only not an international system, it is as far as I know an archaic and poorly defined unit that is not currently in use anywhere. Technically, the question is poorly worded because we are asked to compare a unit with a system of units. Since no system of units consists of just one unit, the answer to the question is any unit of measurement (including one that is part of the international system of units) is not the international system of units. So if the questioner is asking for a currently used system of units that is other than the international system, there are probably many such systems. Any system other than the metric system will do. The one I am familiar with is the English system, also known as the FPS (foot-pound-second) system.
Liters and ounces are both units of volume measurement, but they are not directly comparable because they are part of different systems of measurement. One liter is equivalent to approximately 33.8 fluid ounces. Liters are used in the metric system, while ounces are primarily used in the imperial and US customary systems.
