Some units of measure are easier to calculate with than others. For example, all metric units can be easily multiplied or divided by units of ten to reach another unit of measurement.
Two measurements are equal when they have the same numerical value, for example 1 inch is equal to 2.54 centimeters. To show equality between measurements, they must have the same units, or be converted to the same units for comparison.
Grams and millimeters are units of different measurements (weight and length, respectively) and thus cannot be directly converted.
That is the same as asking "how many teaspoons are in 2 miles". Volume and linear measurements are incompatible units and cannot be converted.
Metric units of measurement are more fun to say.
1-200 in SI units typically refers to the range of values for measurements such as length, mass, time, etc., which are expressed using the International System of Units (SI). For example, 1-200 meters for length, 1-200 grams for mass, and 1-200 seconds for time.

The system of units used for measurements in chemistry is called the International System of Units (SI). It is a globally recognized system that provides a consistent set of units for measuring physical quantities.
