I am reading European engineering publications, and the circle with a slash shows up about half of the time in front of length measurements. For example, Ø15 x 1.12 mm. What does this mean?
The format would make sense if it described a 15mm diameter bolt, threaded with a 1.12mm pitch thread.Wisco52 said:For example, Ø15 x 1.12 mm.
this means a disc of diameter 15mm and thickness 1.12mmWisco52 said:I am reading European engineering publications, and the circle with a slash shows up about half of the time in front of length measurements. For example, Ø15 x 1.12 mm. What does this mean?
A circle with a slash through it is commonly known as the "no" symbol or the "prohibition" symbol. It is a visual representation indicating that something is not allowed or prohibited.
This symbol is often used in public places such as roads, buildings, and products to communicate rules or restrictions. It can also be seen on electronic devices, software, and websites to indicate actions that are not available or allowed.
The origin of this symbol can be traced back to the early 20th century when it was used in the United States to mark alcohol during the prohibition era. It gained widespread recognition and has since been used to represent prohibition or negation in various contexts.
While both symbols may convey a similar meaning of prohibition or negation, they are not always interchangeable. The circle with a slash through it is typically used to indicate something that is not allowed or prohibited, while the circle with an "X" through it is often used to indicate something that is incorrect or invalid.
Yes, there are variations of this symbol that may have different meanings or connotations. For example, a circle with a slash through it and a person's face may indicate a "no entry" or "no trespassing" sign. Additionally, a circle with a slash through it and a specific object or action may represent a prohibition on that specific item or activity.
