US Teaspoons

Is it possible to convert the US volumetric unit of Teaspoon (defined as 5 mL) using this template? I couldn't find it listed. Thank you! Scientific29 (talk) 22:52, 3 May 2024 (UTC)

Looking up references from the [[teaspoon] article, the US standard is "For nutrition labeling purposes, a teaspoon means 5 milliliters (mL)". https://www.govinfo.gov/content/pkg/CFR-2004-title21-vol2/xml/CFR-2004-title21-vol2-sec101-9.xml

The Australian standard is also 5 mL https://www.saiglobal.com/PDFTemp/Previews/OSH/As/as1000/1300/1325.PDF

Bouncing around the web seems to agree that the metric teaspoon is 5 mL.

However, the teaspoon reference 3 https://web.archive.org/web/20201111220418/https://www.nhs.uk/news/pregnancy-and-child/spoons-give-wrong-medicine-doses/ says "These varied in size, with the smallest holding 2.5ml of liquid and the largest holding 7.3ml. A standard dosing teaspoon holds 5ml." Note the qualifier "dosing".

From this, the official size may be 5 mL in many parts of the world, but everyday experience shows that a teaspoon found in your kitchen may vary wildly. I would be very wary of converting teaspoons to any other scale unless I knew what teaspoon was being used. We went through a similar talk a few years ago about converting cups.  Stepho  talk  00:04, 4 May 2024 (UTC)

It's a long time since this was discussed, see Template talk:Convert/Archive December 2016#Teaspoons. The definition of a teaspoon is vague and has varied over time and place so it might not be suitable for a template which would encourage editors to believe that a standard existed.

My biggest teaspoon holds 6 ml, I bought it because I had a coffee mug holding 15 imperial fluid ounces (430 ml; 14 US fl oz), 50% larger than the others that I have. My grandmother had some teaspoons which very like this one, they were tiny, perhaps only 2 ml, 3 ml tops. My mother has a canteen of cutlery containing sufficient for eight place settings. There are sixteen teaspoons of two different sizes - and although I've not measured them, the larger one looks smaller than a dosing spoon (of which we have several, all marked "5 ml"), so it might hold between 4 and 5 ml. --Redrose64 🌹 (talk) 10:03, 4 May 2024 (UTC)

Your grandmother would be mortified at how her money spent on sending you to finishing school was wasted! That is not a tea-spoon, that is an egg spoon! --𝕁𝕄𝔽 (talk) 15:50, 4 May 2024 (UTC)

Close, but no cigar. Martinevans123 (talk) 15:54, 4 May 2024 (UTC)

Pharmacies recommend using measuring teaspoons, not ordinary eating teaspoons, for doses. Otherwise, 3tsp is supposed to be 1tbsp, and 2tbsp is supposed to be 1 fl.oz. That makes 1 tsp slightly less than 5ml. 1 cup is about 236 ml, so about 4.92 ml/tsp. For most uses, that should be close enough. Gah4 (talk) 17:27, 4 May 2024 (UTC)

For the record, many countries have 3 teaspoons = 1 tablespoon (15 mL) but Australia has 4 teaspoons = 1 tablespoon (20 mL). Lesson: teaspoons (and tablespoons) are not good for measuring.  Stepho  talk  23:18, 4 May 2024 (UTC)

Cubic kilometers

Error in convert: Unit name "cukm" is not known. Why not? I recognise that few editors have ever needed to use such a unit [archives only record a passing reference in 2008] but the magma output from a good volcano is measured thus. Such as Phlegraean Fields, which is where I tried to use it. It seems like it should be an easy one to add? 𝕁𝕄𝔽 (talk) 23:34, 21 May 2024 (UTC)

@JMF: {{convert|1|km3}} → 1 cubic kilometre (0.24 cu mi) works. Imzadi 1979 → 23:58, 21 May 2024 (UTC)

For that article, you might want: {{convert|1000|km3|abbr=off|sp=us}} → 1,000 cubic kilometers (240 cubic miles) Johnuniq (talk) 01:23, 22 May 2024 (UTC)

Thank you both. I had persuaded myself that we have CUxx for everything else so obviously it is an inadvertent omission. We don't and it isn't. My apologies for the timewasting question. --𝕁𝕄𝔽 (talk) 09:23, 22 May 2024 (UTC)

But for background, it was this (valid) existing use in the article that persuaded me: {{convert|500|km3|cumi|sigfig=2|abbr=on}} [500 km³ (120 cu mi)] so it wasn't entirely frivolous. --𝕁𝕄𝔽 (talk) 09:29, 22 May 2024 (UTC)

The "cubic" name goes with imperial units such as cumi and cuft. The SI ones use 2 or 3 such as m2 or m3 and their multiples such as km2 or km3. Johnuniq (talk) 09:42, 22 May 2024 (UTC)

Cubic centimetre. --Redrose64 🌹 (talk) 20:53, 22 May 2024 (UTC)

Units of acceleration

Hello. I was wondering if this template can convert units of acceleration? I didn't see it documented so I'm not sure what perimeters to use. What's of particular interest is the conversion between m/s² and g₀, for use on planet and minor planet articles. Thank you. Praemonitus (talk) 14:53, 22 May 2024 (UTC)

If you pass the parameters "m/s2" and "g0" for the units it should work. Nickps (talk) 15:10, 22 May 2024 (UTC)

Thanks! Praemonitus (talk) 22:04, 22 May 2024 (UTC)

The full list of units includes acceleration: Module:Convert/documentation/conversion_data#Acceleration. Johnuniq (talk) 06:50, 23 May 2024 (UTC)

Converting to more than 1 unit

Hello there, I want to convert the thrust of the engine to the article Kuznetsov NK-32 from kgf to kN and lbf but how do I do that? Vitaium (talk) 11:39, 1 June 2024 (UTC)

@Vitaium: Per Template:Convert#Into multiple units: 10 °C (50 °F; 283 K), you would use 14,000 kilograms-force (140 kN; 31,000 lbf). --Redrose64 🌹 (talk) 13:05, 1 June 2024 (UTC)
