Q.No.148: - How many watt-hours are there in 1000 joules?

Ans: -

          1kwhr           =         3.6x10⁶J

          1whr             =         3.6x10⁶J/10³

          1whr             =         3.6x10^6-3J

          1whr             =         3.6x10³J

          1whr/3.6x10³         =         1J
          0.000278whr         =         1J

          1000x0.000278watt hr   =         1000x1J

          0.27778watt hr                =         1000J
