Length

Examples include:

in2cm(x) — inches to centimetres
cm2in(x) — centimetres to inches
conversions involving metres, chains, fathoms, furlongs, leagues, light years, Ångströms, and astronomical units

Available length functions:

in2cm, cm2in, chain2m, m2chain, fathom2m, m2fathom, furlong2m, m2furlong, leage2m, m2leage, lighty2m, m2lighty, angstrom2m, m2angstrom, au2m, m2au.

$\begin{aligned} x &\colon\quad \text{length in inches} \\[0.6em] \mathrm{result} &= x\cdot 2.54 \end{aligned}$

Temperature

c2f(x) — Celsius to Fahrenheit
f2c(x) — Fahrenheit to Celsius
c2k(x), f2k(x), k2c(x), and k2f(x) — Kelvin conversions

$\begin{aligned} x &\colon\quad \text{temperature in Celsius} \\[0.6em] \mathrm{result} &= \frac{x\cdot 9}{5} + 32 \end{aligned}$

$\begin{aligned} x &\colon\quad \text{temperature in Fahrenheit} \\[0.6em] \mathrm{result} &= \frac{\left(x - 32\right)\cdot 5}{9} \end{aligned}$
