Depending on what you want to know, I have two answers...
1. If you unwound and tied together the strands of DNA in one of your cells, it would stretch up to six feet, but they would only be 50 trillionths of an inch.
2. If you could unwrap the DNA you have in all the cells in your body, you would be able to reach the moon and back 6,000 times.
The exact length has been debated, but the best answer is that a human cell's DNA is about 3 meters in length.

If completely unraveled, human DNA would stretch from the Earth to the Moon.
If you stretch it and not unravel it, the distance is on average about 6 ft. (2 m) long, but is a very thin thread.
The single human chromosome on average consists of DNA molecules approximately 2 inches long.
The Physics Factbook [see link below] gives the formula of:
"The length is (length of 1 bp)(number of bp per cell) which is (0.34 nm)(6 ×109)"
Around 3 billion miles
Most sources estimate the number of cells in a human body to be from 5-10 trillion cells. In a human body with 10 trillion cells, the length of DNA would be around 37 billion miles...enough to go to the sun and back about 200 times. It would take 2 days and 7 hours to get to the other end if you were going at the speed of light.
Chromatin is the long strands of DNA that are uncoiled and spread out within the cell nucleus. This uncoiled structure allows the DNA to be accessible for gene expression and replication.
The largest cell in the male human body is the sperm cell, also known as a spermatozoon. It is approximately 50 micrometers long.
There are a number of contenders for the position of smallest cell in the human body. The head of the sperm is on average 5 to 6 micro meters. The flagellum is up to 50 micrometers long. Also some says Granule Cell of the Cerebellum is the smallest cell of the human body it is approximately 4um to 4.5um in size. The size of the RBC also found as around 5 micrometers. In terms of volume most of the scientists suggest that sperm is the smallest cell.
The longest cells are neurons (nerve cells) with a length of 90cm-100cm linking the central nervous system (brain and spinal cord) to other parts of the body.
The longest cell in the human body is the motor neuron that can stretch from the base of the spinal cord to the tips of the toes. These neurons transmit electrical impulses from the brain to the muscles to enable movement.
It would be about 2 meters long. (National Institute of Health)

from earth to the sun and back 30 times eureakascience.com
no, a Bb tuba is 36 feet long if uncoiled.
Uncoiled the Epididymis would be approximately nineteen feet in length
.16 almost 17 feet
If it's DNA you're talking about, a human chromosome has about a meter or two of DNA but its coiled up and then the coils are coiled so it ends up as a compact microscopic lump. Other organisms package the stuff differently
7 metres
If you mean if all of the tubing were uncoiled it would be between 12 and 13 feet long.
The small intestine is a long, narrow tube about 23 feet long. The large intestine is wider, but it is only about 5 feet long.
