Unusual Unit for Tension

**FEND.** · 05-17-2004, 07:31 AM

OK, I know you guys hate answering questions like these which are repeated, but I cannot find any post which is of the same nature with my question.

My question is the tension. When I restring my racquets, the guy just asks whether I want 60, 70 or something like that. Could someone explain what it translates into?

I found another guy to do my stringing who uses pounds but this current man I go to really often and I get good prices. So please anyone?

Maybe another unit, besides kg and lb.

Tell him ur desired tension in kg or lb, and ask him to show ur the converstion chart and calculate the # with his unit in front of u.

Thanks! Not A bad idea. I will do that when I go for restringing and check it out. But just curious has anyone come across such units being used? If so I wouldn't mind if anyone could explain! Thanks again!!

I have never heard of tension at 60 or 70. Are you sure he was not talking about 60 lbs or 70 lbs tension for tennis racquets? Badminton racquet tension is expressed in lbs or kg and nothing else.

Maybe the machine has it's own scaling unit. There must be a conversion chart there. 60 doesn't sound like kg nor pound.

Sounds like newtons, although 60 N = 13.5 lbs is very low for badminton racket strings.

100 N = 22.5 lbs is close to what I have on my strings.

I'd like to see that unit become more popular

Well guys, I went to my racquet shop today 'cause my exams were over

only today so mom brought me there and I asked the man what is my tension? He said it was around 70 and when I asked him to translate it into pounds he said it was 25 pounds!!

So I'm like

lol right now, and I finally found out what string he gave me when I bought the racquet a BG 66 stringed at 25 pounds on my new muscle power 23. Just to let you guys know!!!

So its maybe 25lbs x 3 = 75 units of something?? Anyways I'm gonna test out the racquet in training further and see if I need a restring.

Thanks for the help!

Er... he still hasn't answered your question yet. 60 or 70 of what?!! What's the unit? Is he the only stringer who goes by this idiosyncratic measurement?

mmm yea i noticed that

. Anyways he said that his 'unit' was equivelent to 25 pounds? So I'm still searching for the answer. Any developments will be posted here

Some badminton stringing machines come with a maximum tension of 36 lbs. That stringer has probably assigned a percentage scale of 0% to 100% to correspond with the tension scale of 0 lbs to 36 lbs. 70% of 36 gives you an approximate 25 lbs.

Genius Taneepak!!

sounds like a good answer - i'm still trying to convert between lbs/sq. in and kgs/sq cm.

thought that might have given the answer...

not got there yet tho.. :S

**FEND.** · 05-20-2004, 08:39 AM

Taneepak you really are a genius. Your answer makes more sense than mine, a hellotaa sense.

Thanks for it!

**cappy75** · 05-21-2004, 07:48 AM

Now that would make more sense than saying 60 or 70 alone. Heck! He didn't even quote the figures in percentage

. Still, I think the stringer should quote in the proper units. Not everybody would know what he's talking about... like FEND.'s situation.

Sounds like a reasonable answer. This might especially useful for a drop weight type of machine. With different "weight" for different rackets (tennis, badminton, racket ball), it might be hard to remember all the "conversion chart". Therefore, percentage might be the easiest one for "unit".
