Energy and work:

J = 60 s/1 min × min × J/s <> W × min × 1 h /60 min = Wh

From Wikipedia - J represents (approximately):

• The amount of electricity required to run a 1 W device for s.
• The energy required to accelerate a 1 kg mass at m/s² through a distance of 1 m.
• The kinetic energy of a kg mass traveling at 1.41 m/s.
• The energy required to lift a 101.97 g (3.597 oz) tomato up meters.
• The heat required to raise the temperature of g water from 0 °C (32 °F) to 1 °C (33.8 °F).
• The typical energy released as heat by a person at rest every ms.
• The kinetic energy of a 50 kg human moving at m/s.
• The kinetic energy of a 56 g tennis ball moving at m/s.
• The food energy in about mg table sugar.
