International sport is not used in the metric system, although international sport does use the metric system.
No, not all metric units are part of the International System of Units (SI). The SI is a coherent system of units derived from the metric system, but it is more specific and defined, and not all metric units are included in the SI.
The SI system - International System, after its name in French.
Answer: as far as i know there is no other way to say the metric system besides the metric system! Answer: There are several "metric systems"; the version that is used internationally is called "SI", an acronym for "International System" in French.
Check in the Machinery's Handbook 17'th edition on page 1191 through 1193 for a description of all the metric threads as agreed to by the international congress for thread standardization at zurich in 1898.
SAE is American or standard thread and metric is everything else. The size or diameter is different and the pitch of the thread is different also.

Metric thread pitch is measured directly from crest to crest of the thread form. For example the distance from crest to crest of a M8 x 1.25 MM thread would be 1.25 MM. Another way to measure it would be linear travel per rotation, in which case a M8 x 1.25 MM thread would travel 1.25 MM each rotation.
No, not all metric units are part of the International System of Units (SI). The SI is a coherent system of units derived from the metric system, but it is more specific and defined, and not all metric units are included in the SI.
In an M6 thread, the "M" stands for metric, indicating that the thread is measured in millimeters. The "6" signifies the nominal diameter of the screw or bolt, which is 6 millimeters. This designation is part of a standardized system used for metric fasteners, ensuring compatibility and consistency across different applications.
Metric is an international system of measurements.
The "-6h" in a metric thread callout indicates the tolerance class of the thread. The "6" refers to the nominal diameter of the thread, while the "h" denotes the tolerance grade, which specifies the allowable deviations from the nominal dimensions for the internal or external thread. In this case, it signifies a medium tolerance for fit, commonly used for standard applications. This classification ensures compatibility and proper functioning of threaded components.
The SI system - International System, after its name in French.
The International System of Units (SI) is a revision of the metric system. It is the modern form of the metric system and is the most widely used system of measurement worldwide.
