**The Physics of "***A Liter and a Gram*"

**The original lyrics begin, "I love you
a bushel and a peck". **

This parody version takes things rather to extremes in terms of quantifying
love! The units used:

**1 liter = 0.001 cubic meters
= 1.057 quarts**

1 gram = 0.001 kilograms, which on Earth weighs 0.0022 pounds

1 meter = 1.094 yards

1 Newton (the force which will accelerate a mass of 1 kg at a rate
of 1 m/s^{2}) = the weight of 0.225 pounds

1 Watt = 0.0014 horsepower*

1 poundal (the force which will accelerate a mass of 1 pound at rate
of 1 foot/s^{2})

= 0.138 Newtons = the weight of 0.031 pounds

1 dyne (the force which will accelerate a mass of 1 gram at a rate
of 1 cm/s^{2})

= 10^{-5} Newtons = the weight of 2.25 millionths of a pound
or about the weight of a mosquito

1 foot-pound (the torque exerted by a force of one pound with a moment
arm of 1 foot) = 1.36 Newton-meters

**1 erg = 10**^{-7} Joules
= 2.8 x 10^{-14} kilowatt-hours, or about the energy needed
for a mosquito to do a pushup

**1 calorie (the amount of energy
needed to heat a gram of water by 1 degree C) **

= 0.001 Calories (the kind weight-watchers count) = 4.18 Joules =
1.16 x 10^{-6} kilowatt-hours

**1 degree Centigrade is as
big a change in temperature as 1.8 degrees Fahrenheit**

**Most of the above conversions
were obtained from the Google units converter. For example, type "2.4
meters in yards" into Google. **

There is also a very nice web-based units converter available here.

***One horsepower really is
about the amount of power a horse can provide, at least over a short
period. Click here
