Yes, the variability of the calorie is why it is deprecated (for 61 years);
well, also because it is not coherent. The BTU obviously has exactly the same
problems; if any organization were in charge of Customary/Imperial units, it
would be deprecated too. EIA uses the BTU-IT. (Since the Briti
Dear John,
The BTU and the calorie share a common problem in that they both vary
with temperature. A calorie at 20 °C is not the same as a calorie at
37 °C. And the same is true for any of the BTUs. The differences are
not great but when you multiply these small differences to discuss

That was me, not Pat. I received my BSEE in 1966 and MSEE, and EE in 1968.
Perhaps SI was more prevalent in course VI, but my chemistry, physics, and

course II (but not in things like Naval Architecture) were also rece

To be honest, I'm not a huge "tea-jenny" - I prefer coffee!
I picked Tetleys because they are the most common & popular tea in the UK. In
general, you can assume that Tetleys cater more for the mass market whilst
Twinings aim for the speciality market.
However, as well as the Tetleys,

No question about it. I wish the author had used, at least in the calculations,
SI only; the equations and comparisons would be simpler. However, being used to
the muddle of units seen in the US, the books seems VERY metric. The note from

That's very interesting. I buy Twinings tea, and I had always assumed the

reading your remarks, I looked at both my own stash, and their website.
The offerings in the American line in teabags are all based on 2 g/bag. I

In the UK, tea is not usually sold by liquid measure.
However, in supermarkets & specialist tea shops it is sold by weight (just add
boiling water!)
Tea is another product that is currently subject to prescribed quantities.
Current pack sizes include 125g, 250g, 500g, 750g & 1kg

Coincidentally, I had a beer at lunchtime yesterday that was served in
an imported German glass that had a line printed on the outside of the
