What is the conversion factor to change mg/L to pounds per million gallons?

To convert from milligrams per liter (mg/L) to pounds per million gallons, the factor you need is 8.34. The reason this conversion factor is used stems from the relationship between the units involved.

First, we need to understand that 1 million gallons is approximately 3.785 million liters (since there are about 3.785 liters in a gallon). When you have a concentration expressed in mg/L, it means there are milligrams of a substance in one liter of water. To find out how many pounds are in a million gallons of water with that concentration, you have to consider the conversion from milligrams to pounds and from liters to millions of gallons.

Since 1 pound is equal to 453,592.37 milligrams, you can determine the number of pounds in 1 million gallons by multiplying the concentration in mg/L by the volume in liters of 1 million gallons. When you perform the calculation, you will find that:

• 1 mg/L equals 1,000,000 mg per million liters (because there are 1,000 liters in a cubic meter).

• Therefore, for 1 million gallons, you take 1 mg/L and convert it to pounds using the conversion factor which
