A size 18 hypodermic needle has an outer diameter of approximately 1.2 millimeters (0.047 inches). It is considered a large gauge needle, commonly used for drawing blood, administering fluids, or in procedures requiring thicker fluids. The larger the gauge number, the smaller the needle diameter; thus, an 18-gauge needle is significantly larger than more commonly used sizes like 22 or 25.

The size of a needle is expressed by what?

The size of a needle is typically expressed by its gauge, which is a numerical scale where a higher number indicates a thinner needle. For example, a 30-gauge needle is finer than an 18-gauge needle. Additionally, needle sizes may also be described by their length and type (e.g., hollow bore, straight, or curved) depending on their intended use in medical procedures or sewing.

Do you have to have a big needle to get a big hole for your Monroe piercing?

Whenever you go in for a Monroe piercing, the piercer will take a needle, usually either a 18-16 gauge, and pierce your lip with that. It doesn't leave a big hole at all. But, if you want to gauge your Monroe, then you could have the piercer pierce with a bigger gauged needle, or just gauge it out yourself.


What are the sizes of needles and different gauges?

Needles are measured in sizes, which can vary depending on their type and intended use. In general, the larger the needle size number, the smaller the needle; for example, a size 10 needle is larger than a size 30 needle. Gauges refer to the thickness of the needle, with a higher gauge number indicating a thinner needle; common gauges for medical needles range from 18 (thicker) to 30 (thinner). Different applications, such as sewing or medical procedures, may require specific needle sizes and gauges for optimal performance.

Is a 20-gauge needle larger than an 18-gauge needle?

No, a 20-gauge needle is smaller than an 18-gauge needle. The gauge number indicates the diameter of the needle, with a lower gauge number signifying a larger diameter. Therefore, an 18-gauge needle is thicker and has a larger bore compared to a 20-gauge needle.


What size needle do you use to vaccinate my milking cow beef cow pig and chickens?

Size of the animal and age (which correlates with size) matters here. But I'll do my best. (g = gauge, not grams) Beef cow: 14 g or 16 g needle, possibly 18 g (1" to 1.5") Dairy cow: 16 or 18 g needle (1" to 1.5") Pig: (I think) 14 g 1.5" needle (pigs have thick tough hide like cattle do) Chickens: 25 g 3/4" to 1/2" needle (the smaller the better) You're better off talking to a vet of what size needles are best for each animal.
