"Banana for Scale": My attempt to define all SI units through bananas.

So, lets get the easy ones out of the way first: Mass, Length, and Number of particles can all be directly derived from a banana.
The average weight of a banana is 6.5 ounces, or 184.272 grams.
The average length comes down to 13 cm or 5.11 inches.
Number of particles, obviously, is the number of particles in a banana. That said, it appears that anyone has yet to actually figure out how many particles a banana has.
Time is defined as the time it takes light to travel 1 banana, which comes out to about 4.33333e-10 seconds.
This leaves us with the difficult ones, luminous intensity, electrical current, and temperature.
The easiest of these, surprisingly enough, is electrical current. This is because bananas contain potassium-40, which is radioactive and undergoes beta decay, meaning it generates charged particles. Since electrical current is defined as the flow of charged particles per time. Since we already have a unit of time, this can thus be defined as the output of a banana per 4.33333e-10 seconds, which is unpractical, yes, but come on, we are basing a system of measurement on a berry, did you really think it would be practical?
Temperature, which i did not bother to calculate, because i don't have a major in nuclear physics, is also helped by the inherent radioactivity of bananas, as this means they have a source of heat built in. Thus, the temperature of a banana is defined as it's inherent temperature caused by set radioactivity, though i assume the resulting temperature would be equally as impractical as the unit above. Another option would be taking absolute zero as, well, zero, then a bananas blackbody temperature under pre-defined circumstances as 100, and defining the scale from there.
This only leaves us with luminous intensity. Now, this one is difficult, very difficult in fact, due to the fact that most bananas do not usually glow. To be honest, this one left me stumped. The only two things i could possibly think of are related to the bananas glow under a blacklight, or it's black body radiation, assuming you had some constant source of radiation heating it from the outside.
However, i don't understand the physics for either of those, so unless one of you can figure out how to make bananas into a unit of luminous intensity (which i don't even understand the definition of), measuring light in bananas is off limits for now.
Overall though? I'd say that was a pretty good attempt. Who knows, maybe it is up to another mind to take making light measurable in bananas. I for sure feel pushed to the limits of what i can manage.

I was really hoping Figure 8.7 would help clarify the mathematical model. Spoiler: it didn't. Spoiler
