If the yearly worldwide energy consumption is 80,000 TWh, and a particular earthquake generates 1.6x10^13 Joules of energy.
If we could harness all of the energy from the earthquake, for how long could we power the entire earth?

1$\begingroup$ Look up the conversion rate from J to kWh. Then do the maths. $\endgroup$– hdhondtCommented Jun 6, 2019 at 23:22

$\begingroup$ @hdhondt I don’t understand, the question does not mention KWh, only joules and TWh. $\endgroup$– HishamCommented Jun 7, 2019 at 0:28

$\begingroup$ KWh= kilo Watts-hour=1,000 Wh. TWh= tera Watts-hour=1,000,000,000,000 Wh. The prefixes in most quantities in physics are multiplication by some factor of 1000. $\endgroup$– user137661Commented Jun 7, 2019 at 1:42

$\begingroup$ You should not have to look up anything. You should understand what the relationship is between a joule and a watt-hour. $\endgroup$– G. SmithCommented Jun 7, 2019 at 2:10

1 watt-second = 1 joule, 1 kilowatt-hour = 3.6 megajoules
As this is under homework you should be able to figure it with this info.
