Regular riding uses about 6 wh/km. Riding up hills uses 12 wh/km.
These are not True SI units, but they can easily be converted into
joules.
Your whole message was very interesting.
Sorry to appear to be quibbling about a "small point", but ...
What is the meaning of your symbol "wh"?
I can only assume that perhaps you meant "watt-hours". But the symbol
for watts is "W" not "w". Furthermore, such combinations should not be
written together (because they look like they are supposed to be a
prefix attached to a unit); instead they should be separated by a
space, a raised dot or a dot on the line.
Thus, the symbol for watt-hours should be:
W h
or
W.h
or
W·h
(This last should look like a "W" and an "h" separated by a raised
dot. I cannot be sure the raised dot will trqansmit to your coputer as
it shows on mine.)
As you yourself point out, it would be easy to convert this to joules,
so why didn't you?
