For the metric system i know it goes,
Kilo, hecto, ?, Basic Unit, ?, centi, milli
I don't know two of them, what are they?
The missing units in the metric system are "deci" and "deca". Here is the complete list of metric system units in order of magnitude:
1. Kilo (k): This is a prefix that represents 1,000 units. For example, 1 kilogram (kg) is equal to 1,000 grams (g).
2. Hecto (h): This is a prefix that represents 100 units. For instance, 1 hectometer (hm) is equal to 100 meters (m).
3. Deca (da): This is a prefix that represents 10 units. For example, 1 decagram (dag) is equivalent to 10 grams (g).
4. Basic Unit: This is the base unit of measurement for a particular quantity. For mass, it is the gram (g); for length, it is the meter (m); for volume, it is the liter (L); and so on.
5. Deci (d): This is a prefix that represents one-tenth of a unit. For instance, 1 decigram (dg) is equal to 0.1 grams (g).
6. Centi (c): This is a prefix that represents one-hundredth of a unit. For example, 1 centimeter (cm) is equivalent to 0.01 meters (m).
7. Milli (m): This is a prefix that represents one-thousandth of a unit. For example, 1 milliliter (mL) is equal to 0.001 liters (L).
Remember, the metric system is based on powers of 10, which makes conversions between different units much simpler.
