The new length measure "Line"
Why do we need a new measure of length? Quite simply, all previous measures of length such as miles, meters, feet, cubits, yards, inches, etc. were chosen arbitrarily and different ones are used depending on the region. A common measure of length for all civilizations (whether on Earth or on other planets) must not be chosen arbitrarily, but only scientifically. For this the well-known HI-line (H-one-line, also hydrogen-line) of hydrogen (H) is suitable, because hydrogen is the most frequent chemical element in the universe (approx. 90% of the interstellar matter).

The definition of the unit of measure Line
The Line ("HI-Line") is the wavelength of the characteristic radio radiation of neutral hydrogen in vacuum. The radiation is produced when the spin of the hydrogen electron, relative to the proton in the atomic nucleus reverses (hyperfine structure transition of the hydrogen atom).
Short form for the unit Line
The short form for the unit of measurement Line is ln, for example 1 ln.
Prefixes for the unit of measurement Line
For values larger than 1 ln, the following optional prefixes are available:
1 Dln = 10¹ ln = 10 ln (decaline) 1 Hln = 10² ln = 100 ln (hectoline) 1 Kln = 10³ ln = 1,000 ln (kiloline) 1 Mln = 10⁶ ln = 1,000,000 ln (megaline) 1 Gln = 10⁹ ln = 1,000,000 ln (Gigaline) 1 Tln = 10¹² ln = 1,000,000,000 ln (Teraline) 1 Pln = 10¹⁵ ln = 1,000,000,000,000 ln (Petaline) 1 Eln = 10¹⁸ ln = 1,000,000,000,000,000 ln (Exaline) 1 Zln = 10²¹ ln = 1,000,000,000,000,000 ln (Zettaline) 1 Yln = 10²⁴ ln = 1,000,000,000,000,000,000 ln (yottaline)
and for smaller values than 1 ln are:
1 dln = 10^-1 ln = 0.1 ln (deciline) 1 cln = 10^-2 ln = 0.01 ln (centiline) 1 mln = 10^-3 ln = 0.001 ln (milliline) 1 μln = 10^-6 ln = 0.000.001 ln (microline) 1 nln = 10^-9 ln = 0.000.000.001 ln (nanoline) 1 pln = 10^-12 ln = 0.000.000.001 ln (picoline) 1 fln = 10^-15 ln = 0.000.000.000.001 ln (femtoline) 1 aln = 10^-18 ln = 0.000.000.000.001 ln (Attoline) 1 zln = 10^-21 ln = 0.000.000.000.000.001 ln (zeptoline) 1 yln = 10^-24 ln = 0.000.000.000.000.000.0001 ln (Yoctoline)
Note: For values greater than 1 ln, the prefix is always an uppercase letter, otherwise it is always a lowercase letter. These prefixes correspond to the prefixes of the SI units, only the symbols for deca and hecto are capitalized in Line for uniformity.
For the area measure, the square line serves as the basic unit: 1 ln²
1000 × 1000 ln = 1.000.000 ln² (square kiloline) 1 × 1 ln = 1 ln² (square line) 0.1 × 0.1 ln = 0.01 ln² (square deciline) 0.01 × 0.01 ln = 0.000.1 ln² (square centiline) 0.001 × 0.001 ln = 0.000.001 ln² (square milliline)
For the space measure the cubic line serves as basic unit: 1 ln³
1 × 1 × 1 ln = 1 ln³ (cubic line)
Conversion line ⇄ meter
The wavelength (λ) is calculated from phase velocity (v) and frequency (f) according to the formula: λ = v / f
Inserting for (v) the speed of light in vacuum in meters per second (299,792,458 m/s) and for (f) the hydrogen frequency (1,420,405,751.77 Hz), we get:
1 line = 0.2110611405413008 meters and vice versa:
1 meter = 4.73796359403411 Line.
Conversion Line ⇄ Feet
Taking the above formula and substituting for (v) the speed of light in vacuum in feet per second (983,571,056.43045 ft/s), we get:
1 Line = 0.6924578101748741 Feet and vice versa:
1 Feet = 1.444131303461591 Line.
Conversion Line ⇄ Inch
Taking the above formula and substituting for (v) the speed of light in vacuum in inches per second (11,802,852,677.1654 in/s), we get:
1 line = 8.309493722098489 inches and vice versa:
1 Inch = 0.1203442752884659 Line.
