Diameter: the distance from the center of a plane figure or solid (such as a circle, a cone, a sphere or a cube) to two points on the side, usually represented by the letter "D".

The way to represent the diameter of a circle is: φ plus the letter representing the circle. Such as φ o, φ a, followed by connection = such as φ o = 3 cm.

Money market terminology

Diameter: This is an important data that needs to be standardized when the country issues gold and silver coins. It is not only indispensable for calculating color and weight in production and casting, but also an important basis for standardizing coin issuance to maintain the consistency and credibility of currency form.

The height is h, the diameter is φ, and what symbol is used to express the weight?

M

When you say weight, it is actually the quality in physics. In 1984, the Order on Unified Implementation of China's Legal Units of Measurement issued on February 27th, it was clearly stipulated that only mass has no weight in basic physical quantities, and it was carefully stated: "In people's life and trade, quality habit is called weight."

Mass is one of the seven basic dimensions in physics, with the symbol M, and the commonly used units are mg, G and T..
