4mm = 5/32 inch (= a bit over 1/8 inch)
Realize that 19/32” is between 18/32” and 20/32”. 18/32” reduces to 9/16” and 20/32” reduces to 5/8”, therefore 19/32” is the 1/32 mark between 9/16” and 5/8”.
2mm = just over 1/16 inch. 3mm = almost 1/8 inch. 4mm = 5/32 inch (= a bit over 1/8 inch)
From a design standpoint, 3/32" and 1/8" chains are basically the same except for the width between the plates. Some people believe 1/8" chains are inherently stronger or more durable due to their width. However, there is no strength or durability advantage to being wider.
Comparing fractions: Fractions can be compared when they have a common denominator. For instance, 5/16 inches and 3/8 inches are two measurements on a ruler. In order to compare the two fractions, they must have a common denominator, 16. 3/8 is larger than 5/16.
That's the formula that our calculator uses to find that 3/8 inch to millimeters is 9.525 mm.
Answer: 5/16 as a decimal is 0.3125.
Solution: 1/32 as a decimal is 0.031
That's it! When you convert 1/32 to a decimal, 0.031 is your answer.
If they thought that 1/32 was larger than 1/8, the decimal may help them see that 1/8 is 4 times larger than 1/32.
1/16 scale model is typically about 30 cm long. 1/32 scale is typically about 15 cm long. 1/64 scale is typically about 7.5 cm long. 4WD articulated tractors are somewhat larger and small tractors like the grey Fergy are somewhat smaller for the same scale.
