Metric conversion, 2020

By this time, most conversions between metric units (grams, etc) and regular, i.e., American standard, units (ounces, etc) are pretty well established.

So how is it that Trader Joe’s and Urban Meadow’s brands have different conversions?

This can of TJ beans and this can of Urban Meadow Beans have the same serving size (130 grams) yet different cup amounts! TJ converts 130 grams into 3/4 cup, while UM converts 130 grams into 1/2 cup. That is a difference of 50%!

So which is correct? It is not so simple. According to this online-calculator.org, 130 grams equals .55 cups of water, which is very close to the 1/2 cup mark, but only .38 cups of honey and over a cup of flour.

And what about canned beans?

According the the USDA , 1/2 cup of kidney beans is only 117 grams (not 130)

And according to the Bush’s, the venerable baked beans company, 1/2 cup is 130 grams.

What do you think? Have you seen confusion when it comes to bean serving size conversion?

Product: Tops Marble Composition Book, 7.5 X 9.75 Inches, College Rule, 100 Sheets, White (63796)

Sold by: Tops Products

Cost: out of stock everywhere

I saw this composition book for sale for $8.00. Crazy right? Except this chart really does happen to have Useful Information. It has fractions (and decimals and percents). And temperature conversion. And is written in clear English. For example, under Metric Unit Conversion, the column reads “When You Know: ________ Multiply By: ________ To Find: ________”.

What I do not see are roods (square measure), scruples (Apothecaries’ weight), reams (paper measure), grains (troy weight), or knots (miscellaneous measures). It is also the only chart to include “mass.”

Hidden Highlights

  • 1 hectare = 2.471 acres
  • To write a decimal for a percent, move the decimal point two places to the left. Omit the percent sign;
  • To convert Celsius to Fahrenheit: mutiply by 9, divide by 5 and then add 32.

Product: Staples Graph Composition Book, 9.75 X 7.5 Graph Paper Notebook, Black (not marbled – ed)

Sold by: Staples

cost: $2.00

This Useful Information chart is on the inside back cover of a graph paper composition notebook. The cover is not the typical marble design. Right away I see some cool icons and graphics…the other Useful Information charts 1-3 have only text. Also, this one has a 3-inch ruler! The content is much the same as chart 2.

Hidden Highlights

  • an acre measures ~209 feet on each side
  • A perch of stone is 16 1/2 feet long, by 1 1/2 feet wide, by 1 foot high. (I would call this a low wall, but what do I know?)
