Yes. A metre, Kilogram and second for example.
The concept of precision is applicable to ANY system of units.
A basic unit of weight in the metric system is a Newton and that is not equivalent to 39.37 of any standard units in any standard system.
Decimal refers to the numbering system based on powers of 10, whereas metric is a system of measurement based on meters, grams, and liters as the fundamental units. Decimal can be applied to any numerical system, while metric specifically refers to units of measurement.
Liberia, Myanmar/Burma, and the U.S.A., are the only non-metric countries, and even these are increasingly turning to the metric system.
You use exactly the same instruments to measure speed in the metric system as you use in any other system. For example, a speedometer, or a distance measuring device and a stopwatch. The difference is that these devices are calibrated in metric units, instead of old-fashioned units.
Any metric or non-metric units can be represented by points on the plotted line.
4800.000 is a number: a pure number does not have any metric (nor Imperial) units.
For just about any type of unit, different units are used between the English system and the SI (metric) system. In both systems, there are units for length, area, volume, mass, force, temperature, etc.
It's (any force in metric units of force)/(any area in metric units of area). The most common one you'll encounter is given in units of Pascals. 1 Pascal = 1 newton/square meter
The English system does not have simple relationships of any kind, that is why scientists, and nearly the entire world other than the US, use the metric system.
The metric system is accurate because it is based on standard units that are defined by physical properties of the natural world, such as the speed of light or the mass of a certain volume of water. This makes it precise and consistent for scientific measurements and international communication.
The English system (the historical units of measurement) may be considered the "opposite" of metric (SI), but in fact they are simply different units.
