To all my virtual friends on the list: Have a happy and healthy holiday weekend (to those so celebrating). May Santa bring you all appropriately metric gifts.

I agree with that, Gene.  Relative to cooking, I believe moisture content affects the mass and density more than it affects the volume of most ingredients (flour for example).  I therefore am not entirely convinced that European cooking by mass is ALWAYS superior to cooking by volume. However,

Another important (perhaps dominant) factor is the moisture content. Original message >Date: Fri, 24 Dec 2010 10:00:25 -0600 >From: "James R. Frysinger" >Subject: [USMA:49279] RE: Fwd: Re: centimetre or millimetre >To: "U.S. Metric Association" > >No, I think Martin meant "heaped"

I deduced that on his second usage.  Another good source for bulk and powder density: http://www.powderandbulk.com/resources/bulk_density/material_bulk_density_chart_a.htm Where I have been able to check values, it is generally pretty good for industrial powders, but less reliable than USDA da

No, I think Martin meant "heaped" in another sense -- many crystals stacked randomly atop each other. It's a classic packing problem in mathematical physics. Packing efficiencies can range from roughly 50 % to roughly 80 % depending on the shape of the entities packed into a volume, and whether

Now I understand your prior remark.  We use "heaped" to refer specifically to a brim-fill measure overfilled with a dry ingredient, with the balance in a roughly conical pile above the brim.  I didn't understand why a heaped teaspoon of sugar would have a different density than a level teaspoon

If you can set your keyboard up to the UK English (and get the £ symbol by pressing 3), you should be able to get the "µ" symbol on the German keyboard - I don't remember its exact position, but I noted its existence when working in Germany a few years ago. -Original Message- From: owne

Jim, The values are rounded quite "liberally."  Given their rounding, it really doesn't matter if a cup is 8 fl oz, 236.6 mL, 237 mL or 240 mL, or a teaspoon 1/48 of one of those cups or 5 mL.  Because of their rounding, I recommend using the mass associated with the largest volume given, usua

On its website, the USDA can use the HTML entity µ or µ to make that symbol. I am confident that the USDA can handle that. I have not tried this, but M$ Windows allows one to redesignate their keyboard into various languages. I can set mine up to be English, Greek, German, Spanish, etc. Whethe

If you want to write "µ", you have a number of choices: 1) Get a German keyboard (not always easy in the US or the UK) 2) Type Alt-0181 when using Windows. 3) Go into your favourite word processor and cut-and-paste "µ" from it. -Original Message- From: owner-u...@colostate.edu [mailto:owne

AS I said, the value of 0.81 g/mL is for heaped sugar (ie sugar with interstitial space between the crystals. The individual crystals themselves (with interstitial space removed) have a density greater than 1 g/mL whch is why they sink. Next time you put sugar into a cup of tea or coffee, pleas

Dear all: In Canada, after a brief period of hard conversion, most construction has reverted to soft conversion, simply because of some need for compatibility with the huge US market next door. Wood studs are mostly soft converted imperial dimensioned - a "2x4" becomes a "39x89". Although mos

Dear Bruce and All, These references might help. These have errors like no space between number and unit. In the first one the unit, millimetre, is not even mentioned as it is assumed that all dimensions on Australian building sites are always in millimetres (hence no decimals and no vulgar or
