The 1157 has a 15mm metal bayonet (push/twist) cap, while the 3157 has a plastic wedge (push-in) cap.
I believe it's 0.020 Inch. For example a 14MM bolt head is 0.020" smaller than a 9/16" and 15MM is 0.020" bigger than 9/16". Think of them as in-between sizes of each other.
15mm beads is =- to how many gm?
15mm = 0.000015km
15mm (millimeters) is about 0.6 inch.
If you mean that 15mm is the diameter, then the circumference will be 47.1mm
15mm=1.5cm. 1.5cm=0.015m So, 15mm = 0.015m
3 x 5 x m x m = 15mm
Should be between 15mm or 18mm
% rate = 15mm/10mm * 100% = 150%
