The Decimeter (dm) is useful for medium-sized objects like the length of a notebook (2-3 dm), the height of a water bottle (2.5 dm), or the width of a laptop (3-4 dm). Often used in education and everyday measurements. Nanometers (nm) are critical in nanotechnology, biology (DNA helix = 2 nm wide), and computing (transistors are 3–5 nm). A human hair is ~80,000 nm thick.
To convert between Decimeter (dm) and Nanometer (nm), use the following formulas:
1 Decimeter (dm) = 100000000 Nanometer (nm)
1 Nanometer (nm) = 1e-8 Decimeter (dm)
1 dm = 1 * 100000000 nm = 100000000 nm
2 dm = 2 * 100000000 nm = 200000000 nm
3 dm = 3 * 100000000 nm = 300000000 nm
5 dm = 5 * 100000000 nm = 500000000 nm
13 dm = 13 * 100000000 nm = 1300000000 nm
27 dm = 27 * 100000000 nm = 2700000000 nm
52 dm = 52 * 100000000 nm = 5200000000 nm
