Conversions
Is it strange that I was excited to break out a brand new spray bottle? I pulled it out of storage to replace the old, now broken, spray bottle that contained our daily disinfectant. This new bottle was larger, so I had to figure out how to mix the proper concentration of disinfectant that would be effective at killing dangerous pathogens like avian influenza. I didn't learn much in my high school chemistry class that remained relevant in my adult life. But in situations like this, I am always thankful that Mrs. S taught us an easy way to calculate conversions. I grabbed a piece of scratch paper and drew a long horizontal line. I added 16 oz of water, the capacity of the new spray bottle, at one end. The Rescue disinfectant label told me I needed to mix a concentration of 1 part Rescue with 64 parts water, so I added that to the line. The water units cancel each other out and I am left with how much Rescue I will need to add to the new spray bottle: 16 ÷ 64 = 0.25 oz Rescue....
