The world system of measurements units is based on the metric system (SI).
There is no difference they are the same thingAnswerSI is the current version of the metric system.For example, the centimetre, the calorie, and the litre are examples of metric units, but they are not SI units.
The International Table Tennis Federation (ITTF) started in 1926 and the Laws of Table Tennis included all measurements in imperial units only (feet and inches). In 1937, the metric (metres, centimetres & millimetres) equivalent were added alongside the imperial measurements. In 1947, the metric measurements were made the primary units of measurement with imperial measurements secondary. In 1975 the imperial measurements were omitted from the Laws completely and all measurements were stated in metric units only. So table tennis tables are defined in the Laws of Table Tennis using metric measurements only. An official table tennis table is 2.74m long, 1.525m wide and 76cm high, and the net is 1.83m long and 15.25cm high
The official system of measurements is the SI; it has SEVEN base units.
Meter Volume Weight ====================== Mass Length Time Electric charge All other measurements are combinations of these.
Metric units of measurement are more fun to say.
Almost all scientists use metric units for scientific measurements.
Metric measurements use powers of 10 to create larger and smaller units.
The metric system includes all of those.

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.
the metric system is divisable by units OS ten which makes it simple to convert measurements in meters into other metric units

in the metric system the lines refer to milliliters
-- nanometer -- micrometer (micron) -- millimeter -- meter -- kilometer
Millimetres, centimetres and metres. Metres, litres and grams.
