1. SI system is standardized worldwide, unlike the English system, where there may be differences in different countries.
2. SI system has units that are either 10 times, 100 times, or 1000 times the smaller unit, making it easier to remember, for example, there are 1000 mm per meter, 100 cm per meter, and 1000 meters per kilometer. English system could be anything when converting from smaller to larger units, making it difficult to remember it all, for example, 3 feet per yard, 12 inches per foot, and 5280 feet per mile.
3. When converting from distance to area to volume, the SI units are still 10, 100, 1000, or 10,000 times the other unit, for example, there are 10,000 square meters per hectare and one cubic cm per ml. English system again could be anything, requiring a lot of memorization of conversion factors,or constantly looking up the conversion factors, for example, 43560 square feet per acre, and 0.133680556 cubic feet per gallon.
CommentThe SI system uses powers of ten raised to multiples of 3. It does not use 'centi', 'deka', etc. The centimetre, for example, is not used in SI. Neither does it use the litre.
