Those units are unrelated, and uncompatible - can't be converted. Grams / hour has units of mass / time. Joules or megajoules is a unit of energy.
mega- as a prefix to anything means 1,000,000 as in megahertz, megawatts, megajoules &c. There are 1,000,000 meters in a megameter.
1 kWH = 3.6 megajoules of energy and 1 BTU = approximately 1055 joules.1 kWH = 3412.3 BTUSo a million BTUs would be 3.4123 billion BTUs (3.4 x 109 BTU)However, this is not an exact conversion because kWH is energy exerted over time, while BTU is energy content.(see the related question)
"Watt" is a rate of using energy. It means "one joule per second"."One megawatt per year" means "One million joules per second per year".Clearly, it has no physical meaning.One megawatt-year is equal to roughly 31.56 megajoules. (rounded)One megajoule per year is equal to roughly 0.0317 watt. (rounded)
The "watt" ... (and also the milliwatt, Kilowatt, Megawatt, Gigawatt) ... are rates or speedsof producing or using energy.One Watt means 1 joule of energy per second.2000 MegaWatts means 2000 Megajoules of energy per second.That's the rate or speed at which it produces energy. Continuously.If it runs for 1 hour at 2000 MW, it produces 7,200 Gigajoules of energy.If it runs for 1 day at 2000MW, it produces 172,800 Gigajoules of energy.and so on.

1000 kilojoules = 1 megajoule
The prefix giga means a billion (a thousand millions).
500 MegaJoules

How many kilojoules in 1 megajoules? The answer is 1000. We assume you are converting between kilojoule and megajoule. You can view more details on each measurement unit: kilojoules or megajoules. The SI derived unit for energy is the joule. 1 joule is equal to 0.001 kilojoules, or 1.0E-6 megajoules

35 MegaJoules
It depends on the efficiency of the appliance. If an electric motor has an efficiency of 0.7, then for every 1000 megajoules, 30 megajoules will be wasted as useless heat or sound or other useless energy form.
1 kg alcohol is 29.7 MJ (megajoules).
