Because they said so
In earlier times, the size of a nail was set by the cost of 100 nails in pennies. The names persisted although the prices fluctuated.
That would depend on the type (common, roofing, concrete) and their size as measured like a two penny (2d) nail and so on. For example 60d common nails are 10 to the pound and 2d roofing nails are 225 to the pound.
A pound of 10 penny (10d) galvanized nails typically contains about 30 to 35 nails, depending on the specific size and manufacturer. This variation occurs because the weight of individual nails can slightly differ based on coating and production processes. If you need a precise count, it's best to refer to the packaging or manufacturer's specifications.
In value, a penny is smaller. In size, a dime is smaller.
There are 225 2d roofing nails in a pound. If you need something longer like 1.75 inches that would be a five penny (5d) and there are only 145 in a pound.
It is a measure of the size of the nail, the term dating back to the 1500s. The penny nail size was originally the price in pennies of 100 nails of that size.
The term "penny" in nail sizing is derived from the British system where nails were sold by the pennyweight. The number associated with each size referred to how many pennies it took to buy 100 nails of that size. For example, a 10d nail cost 10 pennies for 100 nails. This system has been retained in modern nail sizing for historical reasons.
A 16 penny nail is typically made of steel, which provides strength and durability for various construction projects. The term "16 penny" refers to the nail's size and weight, with longer nails typically having a higher penny size.

"Penny turtle" is a term used to describe freshwater turtles that are found in our lakes and ponds. They are referred to as such because they are very small as juveniles, about the size of a penny, and grow up to the size of a dinner plate.
Many different size nails have 'ribs' on them.They are to make it harder for the nail to be pulled out.A 'spiral' ( ardox ) nail is even harder to pull out.
Yes. d is the symbol for a British pence, which is like an American penny. I'll answer the question you didn't ask: why do they use pennies as the unit of measure of nails? Many years ago nails were sold loose, and they were counted out rather than being weighed. The number of pence, or cents, 100 nails in that size would cost you many, many years ago determined the "penny" size. If 100 3-1/2" nails cost 16 pence, they were considered "16 penny" nails. (This also meant there weren't standard nail sizes--if Tom's Hardware charges 16d for 100 3" nails, and Dick's wants 16d for four inch nails. you'd have to go to Tom's for all your nail needs.)
That would depend on the type (common, roofing, concrete) and their size as measured like a two penny (2d) nail and so on. For example 60d common nails are 10 to the pound and 2d roofing nails are 225 to the pound.

8p nails or 8 penny nails, more properly written as 8d nails, are nails that are 2.5 inches (65 mm) long. The unit of measure , the penny, derives from the cost of 100 nails in 15th century England. This way of describing nails is no longer in use in England and survives only in the US.
