hi… please dont laugh… can anyone tell me how to read 1 inch in cm and what is 1-5/8" in cm, is it 1 inch and 0.58 inch or ?? please help thanks!!!

1 foot = 12 inches

1 inch is devided into 8 or 16 depending on what ruler you are using.

1 5/8 = 1 inch and 5 of 8 segments between the 1 inch and the 2 inch mark.

the result of the 5/8 is not 0.58 but 0.625 which is the result of 5 divided by 8

Hope this helps

you have only to divide front number by the numer behinde /

if you did so you can fill the result into a converter like this http://www.digitaldutch.com/unitconverter/

or you are just good at maths

I’m from Europe (Galicia).

1’ = 12’’

1’’ = 2.54 cms

As in any other thing: 1/4 = 0.25 , 1/8 = 0.125, 1/16 = 0.0625…

If you’re going to shape, do you a favor and use a measure tape in foots and inches… is what i do. You can also find cheap measure tapes in both inches and cms. I have all the numbers in inches when talking about surfboards and feels way easier than converting everything from inches to cms.

As mentioned before, 1 inch = 2.54 cm, 1 5/8 inches = 1.625 inches ( 1 + ( 5/8)) = about 4.13 cm.

The easiest way to look at something like that in specifications is to separate the fraction ( 5/8) from the integer ( 1 ) and convert it to decimal notation and then add that to the integer, that is for example;

8 3/4 inches = 8 + ( 3/4 ) inches = 8 + ( 0.75 ) inches = 8.75 inches.

For surfboards ( and small boats ) , typically you get measurements in 1/8 inch increments, so for ease of use

1/8 " = 0.125 "

2/8" = 1/4" = 0.250"

3/8" = 0.375"

4/8" = 2/4" = 1/2" = 0.500 "

5/8" = 0.625"

6/8" = 3/4" = 0.750"

7/8" = 0.875"

so that , again as an example, if you wished to convert 3 3/8" to cm you’d have (3 + 0.375)" and then multiply by 2.54 to get 8.5725 cm…8.6 cm ( or 86 mm, rounding the figure to the nearest millemeter ) would certainly be close enough.

It’s a frequently irritating system, one we should perhaps have gotten rid of around 1805 when Thomas Jefferson suggested going to the then-new system of meters, kilograms and liters.

hope that’s of use

doc…

About the same time we should have gotten rid of the Electoral College.

You know, at about the same time they brought in decimal money ( rather than pence, shillings, pounds, half crowns, guineas and so forth , due to Robert Morris of New York) which was ( forgive the term ) revolutionary …kinda odd that they didn’t go to metric measurements…

Though there was one state legislature that debated a law making pi equal to three…
