Most Fractional Rulers are based on the English measuring system where scales are graduated in units of one inch and fractions of an inch.

Decimal Rulers have graduations or marks which are based on the decimal system such as 0.5, 0.25, 0.1, 0.05, etc. Fractional Rulers have graduations or marks based on fractions, for example 1/2", 1/4" 1/8", 1/16", etc. Unless the 33mm nut or bolt that you need to remove is rounded a 1 5/16th socket. A 1 5/16 standard size socket is 33.34mm which is a little bit bigger than a 33mm socket but it is the standard size socket that best fits over a 33mm bolt. There are two types of scales commonly used on rulers Fractional and Decimal. A 33mm metric socket is 1.29921 inches in size which most closely matches a 1 5/16 standard size socket.

You can set the pixels per inch (PPI) according your own device. If you would like this online ruler in actual size, So i set the default pixels per inch(PPI) is 100.7 for myself.

I found the markings are not very accurate at 30cm, I google the PPI reference and found 100 PPI to my screen,Īfter i measure the size of virtual ruler by a actual ruler, The diagonal screen is 15.6"(inches) of my laptop computer, resolution is 1366x768 pixels. 3.25" = 3 1/4"Īdjusting this virtual ruler to actual size

are there any other advantages? Are these valid? Any disadvantages of bigger tube (less room in a top-feeding rifle?) 50 BMG) where you want to hold the scope as rigidly as possible.īigger tube equals more room for erector travel and so more elevation/windage adjustment at ultra-long ranges.įrom those who know optics. Doneīut got thinking about it and the three advantages of bigger tube seem to be:īigger tube equals more potential light transmission.īigger tube equals more surface/grip area for rings (perhaps important with heavy-recoiling calibers such as. the result: 1 mm 0 35mm 1/4 inch Male TS to 2 RCA Male Adapter Cable. my answer: I like my existing mounts and base, they work well the 30mm I demo'd was superb and I had no issues with it. 039370078740157 inches using the online calculator for metric conversions 8: d. Had an interesting conversation at the range yesterday about tube diameter and the advantages of bigger tubes.Ĭonversation came when another shooter wondered why I would order a 30mm USO when I could have had a 35mm tube.
