IMPERIAL VS METRIC
Measurement stands out as the most common problem in the hose business, as in many other jobs. On the basis of this problem, which arises from the fact that the whole world does not have a common unit for measurement, the "imperial"more commonly used with units of measure"metric” lies the difference between units of measure. In addition to all these, the "" which is used to express pipe and hose diameters in Turkey,finger” is added, things turn into a mess.
Also, there is a problem arising from the way the pipe and hose dimensions are expressed, which creates a special problem for the hose, which is a complete disaster, the communication process between the buyer and the supplier.
Especially when pipes are used to name pipe sizes, "nominal diameter” statement is responsible for all problems. When the inner or outer diameter differences are added to all these due to the wall thicknesses….. It is best not to continue any further.
Inner diameter is what matters in the hose. You can express it as metric, finger or inch. Here "fingerIt will sound funny to you, but the number of people who hesitate to say "I wonder which finger should I use" is too high to be underestimated. “fingerthe expression "inchIt is an expression that corresponds to ".
The cycle is as follows; 1 inch = 1 finger = 25.41 mm
in our "fingerAlthough I tried to find out where the expression ” came from, I could not find any definite information, so I would like to pass by making a simple but logical assumption about it. When making some measurements, we take something as a reference, for example, a span is around 20-22 cm for an average man. An individual who learns this can roughly make simple measurements using the mix when needed. This "fingerFrankly, I predict that the issue of ” is based on the width of a master's thumb when estimating himself in diameter measurement, and then this is continued by apprentices who learn by seeing, who are completely devoid of technical knowledge, who grew up with that master. It seems like a very logical course of action, according to our scenario. However, I have shared this article with you in order to prevent this mistake, which sometimes even results in financial losses, based on the experience of meeting dozens of customers who want to buy a hose using finger length, from those who try to measure by inserting their fingers into the hose.
If you are going to buy a hose, simply measure the inside diameter of the hose using the unit of measurement you want (preferably in mm). If you do not have a hose, you need to measure the outer diameter of the object you want to attach the hose to, so that you can attach the hose you bought to that object.
