What rhymes with units of energy?
unit·s of en·er·gy

Because energy is defined via the SI unit for energy is the same as the unit of work – the joule, named in honor of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton-metre and, in terms of SI base units An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt. One eV is equivalent to 1.60217653×10^−19 J. In spectroscopy the unit cm−1 = 0.000123986 eV is used to represent energy since energy is inversely proportional to wavelength from the equation . In discussions of energy production and consumption, the units barrel of oil equivalent and ton of oil equivalent are often used. When discussing amounts of energy released in explosions or bolide impact events, the TNT equivalent unit is often used. 1 ton of TNT equivalent is equal to 4.2 × 10⁹ joules. Therefore, 1 kt TNT is 4.2 × 10¹² joules, and 1 Mt TNT is 4.2 × 10¹⁵ joules. Note that torque, the "rotational force" or "angular force" which causes a change in rotational motion is typically expressed in newton-metres.
