How would you estimate the number of spark plugs in the state of California?

Question

Anonymous · Accepted Answer

America is a wealthy country, so it's somewhat safe to assume that there are
slightly less that 1 car per person (facotring in too young to drive, too old to
drive, people who don't drive, etc.).  California is one of if not the
wealthiest per capita state in America, so let's round up to one car per person.
A rough estimate of the population of california is 40 million or so.
Cars have one spark plug per cylinder, and it's also somewhat safe to assume
that the average number of cylinders per car in California is around 6.
Therefore, the calculation is as follows:
(pop. of California) * (1 car per person) * (6 spark plugs per car) =
(40mil)*(1)*(6) = 240 million spark plugs in claifornia.

Population in California = 33 million (approx)

No of members in household = 2.5 members per household

No. of households in California = 33 million / 2.5 = 13.2 milliom

Car ownership each household = 1.5 cars (approx)

No . of cars in California = 13.2 million * 1.5 cars = 19.8 million cars

No of cylinders in a car = 6(approx)

No. of sparkbulbs in a car = 12 (approx)

No. of estimated Spark bulbs = No . of cars in California  * No. of sparkbulbs
in a car

Considering California has 40m population. There would be atleast 30 m adults.
Almost everyone driving a vehicle. So close to 25 million vehicles. each having
1 spark plug. So total of 25m spark plugs
