µ and Parts Per …

When you measure the concentration of a substance in water, you can express it in various ways. You have to pay attention to units when converting from one way to another.

A liter of water weighs 1 kilogram, which is 1000 grams.

A milligram is 1/1000th (a thousandth) of a gram. 1mg = 1 milligram = 0.001g

A microgram is 1/1000000 (a millionth) of a gram. 1ug = 1µg = 1 microgram

Note that last line, because it’s important. The symbol µ is the greek letter “mu”. In measuring, it’s used to mean “micro”, or “millionth”. (To type µ, hold down the Alt key, type 230 on the numeric keypad, and then release the Alt key). Since it’s difficult to type, it’s often written using the letter “u”. Make sure you understand the difference between a milligram (mg, 1/1000th or a gram) and a microgram (µg, ug, 1/1000000th of a gram). A milligram is thousandth, not a millionth. It’s a little confusing sometimes.

A microgram is a millionth of a gram, so it’s a billionth of a kilogram. Since there are 1000 grams in a kilogram, and 1,000,000 micrograms in a gram, there are 1,000,000,000 µg in a kilogram. All this is basic high school science.

More people make the same mistake. This time someone in Austrailia, and the story was picked up by a Los Angeles environmentalist. Again mg is confused with µg, making the results 1000 times as high
