How long is a chromosome?

Chromosome 1 is the longest human chromosome at 245,203,898 base pairs (bp) according to the sequence. And the distance between base pairs along the sugar-phosphate backbone of DNA is about 0.33 nanometers (nm). Thus the total length

$={\frac {0.33\mathrm {nm} }{\mathrm {bp} }}\times 0.25\times 10^{9}\mathrm {bp} \times {\frac {\mathrm {m} }{10^{9}\mathrm {nm} }}=0.08\mathrm {m}$

So the largest human chromosome is almost almost ten centimeters in length!

The SI unit of inductance is the henry

${\mbox{H}}={\dfrac {\mbox{Wb}}{\mbox{A}}}={\dfrac {{\mbox{V}}\cdot {\mbox{s}}}{\mbox{A}}}={\dfrac {{\mbox{m}}^{2}\cdot {\mbox{kg}}}{{\mbox{s}}^{2}\cdot {\mbox{A}}^{2}}}={\dfrac {{\mbox{m}}^{2}\cdot {\mbox{kg}}}{{\mbox{C}}^{2}}}$

${\dfrac {\mbox{Wb}}{\mbox{A}}}={\dfrac {{\mbox{kg}}\cdot {\mbox{m}}^{2}}{{\mbox{C}}^{2}}}$
