Hydraulic hose sizes are usually expressed in inches.
Common hydraulic hose sizes include 1/4 inch, 3/8 inch, 1/2 inch, 5/8 inch, 3/4 inch, 1 inch, and more.
The size of the hydraulic hose will affect its pressure, flow, and connection method. Therefore, when selecting a hydraulic hose, it is often necessary to convert millimeters into inches according to actual needs and choose the most suitable hose size.

History/origin: An inch is a unit of measurement that is equal to 1/12 of a foot, or 2.54 centimeters. It is believed to have originated from the width of a thumb, as "inch" comes from the Latin word "uncia," meaning "one-twelfth part." The use of inches as a unit of measurement dates back to the 7th century, when it was used in England as a standard for measuring lengths and distances. Today, it is still commonly used in the United States and the United Kingdom, particularly in industries such as construction, engineering, and manufacturing.

Preguntas frecuentes
What is a millimeter?
A millimeter, sometimes called a millimeter, is a metric unit of length that is equal to one thousandth of a meter, while the meter is the base unit of length in the International System of Units. Thus, one meter is equal to 1000 millimeters. One centimeter is equal to 10 millimeters. 1,000 micrometers or 10,00,000 nanometers are equal to 1 millimeter. Both the millimeter and the inch are units used in mathematics to measure length. The millimeter is defined by the International System of Units, which is used in the International Measurement System, while the inch is used in the United States Customary Measurement System.
What is an inch?
In both the British and American measurement systems, the inch (abbreviated as inches) is a unit of length. It should be equal to 136 yards or 12 feet. This comes from the Latin word for "one twelfth". The inch is a unit of measurement that is 1/36 of a yard in the British Imperial and American Customary measurement systems.
Which countries use the inch?
The United States is the country that uses the inch the most, but many people in the United Kingdom still use the inch as well. In the United States, the inch is the standard for architecture and engineering. The inch is also commonly used to determine the height of a person or the size of a television screen.
Although the UK has officially adopted the metric system, inches are still used in some areas, especially in architecture. This is due to the historical influence of the imperial system. In the UK, inches are also used to measure height and items that are traditionally measured this way, such as vinyl records.
