A recent home energy bill indicates that a household used 335335 kWh (kilowatt‑hour) of electrical energy and 165165 therms for gas heating and cooking in a period of 1 month. Given that 1.00 therm is equal to 29.329.3 kWh, how many milligrams of mass would need to be converted directly to energy each month to meet the energy needs for the home?
