The universe's massergy comes in two forms, the dense matter, and the
very-not-dense energy. We use mass (kg) to
count matter, and energy (Joules, J) to
count energy.
Joule | (m2·kg·s-2) | Energy. The potential to do work.
Often a potential field with something to ready to fall through it. |
force·distance | (m·kg·s-2)·(m) | A weight waiting to fall some distance. |
mass·accel·distance | (kg)·(m·s-2)·(m) | A mass, trying to accelerate, lifted for some distance, and
thus ready to fall. |
mass·velocity2 | (kg)·(m·s-1)2
(kg)·(m2·s-2)
| A mass in motion, reluctant to stop. |
mass·c2 | (kg)·(m·s-1)2
| Conversion between the mass and energy flavors of massergy. |
W·s | (m2·kg·s-3)·s | Watt·second: Some time's worth of power. |
V·A | (m2·kg·s-2·A-1)·(A) | Volt·Amp:
Some electrons (a current), upstream in a voltage (electric potential
difference). |
Wb·A | (m2·kg·s-2·A-1)·(A) | Weber·Amp:
Some electrons, upstream in the voltage created by some magnetic flux
through the conductor. |
Pa·m3 | (m-1·kg·s-2)·(m3) | Pascal·volume: A hunk of some presure or stress. |
F-1·C2 | (m-2·kg-1·s4·A2)-1 ·(s·A)2 | Coulombs2/Farads:
A capacitor, of some roominess (F), with charge (C) stuffed in against
itself. |

Notes:
nuclear phase transition requires particle energy order 2 GeV [AmSci '98 SepOct p449]
Right on edge of oom 1e-9 J. If turns out to be <2 GeV, should be 1e-10 J.
I'm not clear on how speculative this model is. Could check this.
nucleon excitations: delta 290 MeV, N* 500 MeV [AmSci v86 '98 SepOct p451]

1 jelly donut (JD) = 106 J
1 kWh = 3.6 JD
1 flashlight battery (D cell) = 1.6 × 104 J = 0.016 JD
1 mosquito pushup = 1 erg = 10-13 JD
1 barrel of oil = 6 × 109 J = 6000 JD
1 pizza (p) = 107 J = 10 JD (medium, with sausage and pepperoni)
1 Pizza (P) = 1017 J = 1011 JD (one-half of the energy released
in the annihilation of a pizza and an antipizza)

From [World Factbook 1996]:
world Electricity:
capacity: 2,773,000,000 kW (ie 2.8e12)
production: 11.601 trillion kWh
consumption per capita: 1,937 kWh (1993)
US Electricity:
capacity: 695,120,000 kW (ie 0.70e12)
production: 3.1 trillion kWh
consumption per capita: 11,236 kWh (1993)
Metabolism of glucose quoted as 686 kcal/mol. Sigh. Ok...
mol is 6.022 × 1023 molecules, and kcal is 4184 J.
So metabolism of a glucose molecule yeilds 0.4766 × 10-17 J.
US per capita primary energy consuption is ~220 million Btu.
