Metric Confusion? Don’t Worry About It
RATE

Are you confused by the metric system measures – grams and milligrams – commonly used to detail nutrition information on nutrition labels, and in your diabetes eating plan? You’re not alone. In fact, some people are so intimidated by grams and milligrams they find it very difficult to think about nutrition issues at all. If you have diabetes, however, you really must be equipped to think about nutrition issues – your long term health is at stake. So, how important is it for you to understand metric measures?

Metric system is logical

It is true that the metric system is logical – a gram is a measure of mass (weight), a milligram is 1/1000th of a gram and a kilogram is 1000 grams. Metric prefixes are the same for volume (milliliter) and distance (kilometer) too. The problem is there is no logical relationship between metric measures and common U.S. measures. A kilometer is 0.6241 U.S. miles, and a liter is 2.113 U.S. pints. Along those same lines, knowing there are 28.35 grams in a U.S. ounce is a conversion that’s impossible to make meal after meal. But, is it necessary?

In September, 1999, NASA’s $327 million Mars Climate Orbiter promptly crashed upon its arrival due to mix-ups between metric and U.S. measures. Making accurate conversions is very important in rocket science, but diabetes self-management is not rocket science. The truth is you don’t need to know what a gram actually is.

You simply need to know that there happens to be 15 of these “gram things” of carbohydrate – one carb choice – in a 3 ounce piece of white potato, and in ⅓ cup of cooked rice, and in a medium apple, and in one tablespoon of maple syrup. And, you need to know how many of the “gram things” of carbohydrate you should be eating each meal.

Trying to mix metric and U.S. measures led to the crash of the Climate Orbiter on the surface of Mars, but don’t let your anxiety about the metric measures used with in nutrition information crash your diabetes self-management effort. You can count carbohydrates perfectly, and still have no idea what a gram actually is. So, don’t worry about it.
