A sense of scale
Since 20 Nov 2022, Xe11 is adding the conversions to the recipes, most importantly the SI units, which was established in 1960.
m

Length: metre Defines the metre as the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458th of a second 
kg

Mass: kilogram Defines the kilogram by defining the Planck constant to be exactly 6.62607015×10^{−34} kg⋅m^{2}⋅s^{−1} 
s

Time: second Defines the second by taking the fixed numerical value of the caesium frequency, Δν_{Cs}, the unperturbed groundstate hyperfine transition frequency of the caesium 133 atom, to be 9,192,631,770 when expressed in the unit Hz, which is equal to s^{−1}. 
A

Electric current: ampere Defines the current by fixing the elementary charge e to be exactly 1.602176634×10^{−19} C (coulomb), which means an ampere is an electrical current equivalent to 10^{19} elementary charges moving every 1.602176634 seconds or 6.241509074×10^{18} elementary charges moving in a second.
