Converting Between PPM and PPB

This video tutorial explains how to convert between ppm (parts per million) and ppb (parts per billion), which are units used to measure low concentrations. It covers the conversion factor that 1 ppm equals 1000 ppb and provides examples to illustrate the conversion process in both directions. The video also summarizes the key points and provides practice examples to reinforce understanding.

What do ppm and ppb stand for in terms of concentration units?

• Parts per meter and parts per block

• Parts per million and parts per billion

• Parts per molecule and parts per base

• Parts per minute and parts per byte

How many parts per billion are equivalent to 1 part per million?

• 100

• 1,000

• 10,000

• 100,000

If a solution has a concentration of 0.35 ppm, what is its concentration in ppb?

• 35 ppb

• 350 ppb

• 0.035 ppb

• 3.5 ppb

What is the first step in converting 0.07 ppm to ppb?

• Subtract 1,000

• Multiply by 1,000

• Divide by 1,000

• Add 1,000

After converting 0.07 ppm to ppb, what is the resulting concentration?

• 700 ppb

• 7 ppb

• 70 ppb

• 0.7 ppb

To convert 160 ppb to ppm, what operation should be performed?

• Subtract 1,000

• Add 1,000

• Divide by 1,000

• Multiply by 1,000

What is the concentration in ppm when 160 ppb is converted?

• 0.016 ppm

• 16 ppm

• 1.6 ppm

• 0.16 ppm

What is the conversion factor used to go from ppm to ppb?

• Divide by 1,000

• Divide by 100

• Multiply by 1,000

• Multiply by 100

If 0.5 ppm is converted to ppb, what is the resulting concentration?

• 50 ppb

• 5 ppb

• 500 ppb

• 5,000 ppb

What is the relationship between the numbers in front of parts per billion and parts per million?

• The numbers are always equal

• The number in front of ppb is always larger

• The number in front of ppm is always larger

• The number in front of ppb is always smaller
