The 'd' in 16d nails stands for 'penny'
The "D" in 16D nails stands for ""penny", which is a standard unit of measurement for nails. The "D" is derived from the Roman coin, the denarius, which was also the name for an English penny. The penny system of measurement for nails originated in England, where the price of 100 nails of a given size was used to determine the size designation. For example, a hundred 3-and-a-half-inch nails cost 16 pennies, hence the term "16-penny nails".
The penny system is an archaic term that dates back to the time when nails were hand-forged, one at a time. The system remained in use in England until the 20th century but is now obsolete there. Nails are still designated in penny sizes in the United States. In Canada, nails are specified by type and length and are manufactured to imperial dimensions.
The "D" in 16D nails is thus a holdover from the denarius coin and the English penny. It is used to indicate the length of the nail, with a larger number indicating a longer nail. For example, a 2D nail is 1 inch long, a 16D nail is 3.5 inches long, and so on.
The penny size of a nail is also related to its diameter or thickness. The higher the gauge number, the thinner the nail. Nails under 1+1/4 inches, often called brads, are sold with only a length designation or with length and wire gauge designations.
The "D" in 16D nails, therefore, stands for "penny", which is an archaic term for a standard unit of measurement for nails, indicating their length and diameter.

The penny system is a special classification of nail sizes
The penny system, or the ""d"" system, is a special classification of nail sizes that originated in England. The ""d"" in this system stands for "penny", which was a unit of currency in England during the time of Roman occupation. The letter "d" is associated with the Roman coin called the "denarius", which had the same value as an English penny.
The penny system was used to indicate the price of a set number of nails of a given size. One explanation for the system's origin is that a hundred 3.5-inch nails cost 16 pennies, so they became known as 16-penny or 16d nails. Another explanation is that one 3.5-inch hand-forged nail cost 16 pennies. The system has persisted even in modern building codes, and retail boxes of nails are marked with both the penny size and the length in inches.
The penny system is a way to standardise nail sizes, with the length of a nail designated by its penny size. The abbreviation "d" is used for "penny", so a 16d nail is a 16-penny nail, an 8d nail is an 8-penny nail, and so on. This system is still used in the United States, although it is no longer used in England.
The penny size of a nail corresponds to the measurement from the head to the tip, or the nail length. The diameter of the nail also varies based on the penny size, depending on the nail type. A larger number indicates a longer nail, and every increase or decrease in the number corresponds to a change in length of 1/4 inch. For example, a 2d nail is 1 inch long, a 4d nail is 1.5 inches long, a 6d nail is 2 inches long, and a 16d nail is 3.5 inches long.
In addition to the penny system, nail sizes can also be indicated by their gauge, which refers to the thickness or diameter of the nail. The higher the gauge number, the thinner the nail. Nails can also be classified by their type, such as common, sinker, or short nails, which differ in physical size and coating.

The penny system originated in England
The 'D' in 16D nails stands for "penny", with 16D referring to a 16-penny nail. This system of indicating nail length originated in England during the time of Roman occupation. The "D" is associated with the Roman coin, the denarius, which was also the name for an English penny. Nails were hand-forged at the time, and it is said that a hundred 3.5-inch nails cost 16 pennies, hence the term 16-penny nails.
The penny system, which is also referred to as the Carolingian monetary system, has a long history in England. The term "penny" is derived from the word "denarius", a Roman coin, and was used in England as early as 785. The penny was originally minted in silver, but from the late 18th century, it was minted in copper, and later, in 1860, in bronze. The penny remained the principal currency in Europe for several centuries until its value diminished due to debasement.
The etymology of the term "penny" is uncertain, but it is believed to be derived from the Low Franconian form of Old High German "pfant", meaning "pawn" or "pledge". It may also be derived from the West Germanic word for "frying pan", owing to its shape, or from the Latin "pondus", meaning "pound".
The penny system was used in England until Decimal Day in 1971, when it was replaced by the decimal system. The plural of "penny" is "pence" when referring to an amount of money and "pennies" when referring to individual coins. The penny has also been used in the US, with the first one-cent coins minted in 1793, and the Lincoln cent introduced in 1909.

The system is based on the price of 100 nails of a given size
The "D" in nail sizes, such as 16d, refers to the penny size of the nail. The penny system is a special classification of nail sizes that originated in England, where the nail size was originally named after the price of 100 nails of a given size. The "d" is derived from denarius, a Roman coin with the same value as an English penny.
The penny system is an archaic term that dates back to when nails were hand-forged and sold in bulk. The system is based on the price of 100 nails of a given size, with the larger nails costing more per hundred. For example, 100 3-1/2 inch nails cost 16 pennies, hence the term "16-penny nails". The system is no longer used in England, but it persists in the US and Canada, where nails are still designated in penny sizes.
The penny size of a nail is a standard unit of measurement that indicates the nail's length and diameter. The higher the penny size, the longer the nail. For instance, a 2d nail is 1 inch long, a 4d nail is 1.5 inches long, a 6d nail is 2 inches long, and so on. The penny size also affects the diameter of the nail, with the diameter generally increasing as the penny size increases.
The penny system is not the only way to measure nail size. Nails are also commonly sold by length, which is a less confusing method. Additionally, nail gauge sizes indicate the thickness or diameter of a nail, with higher gauge numbers corresponding to thinner nails. The gauge is the same as the wire diameter used in the manufacture of the nail.

The 'd' in 16d nails is associated with the Roman coin, the denarius
The "d" in 16d nails stands for ""penny", with 16d referring to a 16-penny nail. This system of indicating nail length goes back to the time when the Romans occupied what is now England. The "d" is associated with a Roman coin called the denarius, which was also the name for an English penny.
The denarius was one of the most widely circulated coins of the ancient world. The word "denarius" is derived from the Latin "deni", meaning "containing ten", and its value was originally ten asses (an "as" being the smallest denomination issued at the time). In Roman times, 240 denarii were minted from one Roman libra (pound), so one pound (libra) contained 240 denarii. Before England moved to a decimal system in 1971, a penny was worth 1/240 of an English pound sterling, and its symbol was "d", derived from the Roman denarius.
The "d" in 16d nails is a relic from the time when nails were hand-forged one at a time. There are two theories as to why the "d" is used in this context. One theory suggests that a hundred 3-and-a-half-inch nails would have cost 16 pennies, thus becoming known as 16-penny nails. The other theory suggests that the number and the "d" indicate that one 16d (3-and-a-half-inch) hand-forged nail cost 16 pennies.
The "d" designation persists even in modern building codes, and retail boxes of nails are marked with the penny size as well as the length in inches.

A 16d nail is 3.5 inches long.
To determine the length of a 'd' nail, divide the "d" number by 4, then add 1/2 inch. For example, a 4d nail would be (4/4 =) 1 + 1/2 inches long.
