Q: When using {{convert}} why does the answer sometimes seem a bit off?
A: This template takes into account the precision of the supplied value and generally rounds the output to the same level of precision. If you need to change from the default output precision, see
rounding.
Note: This can cause whole numbers that end in one or more zeroes to be converted less accurately than expected.
Q: What are all the possible units (kg, lb, m, cm, ft, in, °C, °F, km, mi, nmi, mph, km/h, and so on)?
Q: I've been using Convert for some time and am pretty comfortable with its basic features. Does it have other features which it would be worth my while to learn about?

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!

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.

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. --

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!

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.

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)reply
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: {{convert|1|km3}} → 1 cubic kilometre (0.24 cu mi) works. Imzadi 1979→ 23:58, 21 May 2024 (UTC)reply
For that article, you might want: {{convert|1000|km3|abbr=off|sp=us}} → 1,000 cubic kilometers (240 cubic miles)

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. --

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. --

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.

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.

If you pass the parameters "m/s2" and "g0" for the units it should work.

Hello there, I want to convert the thrust of the engine to the article

In the third table at
Danube#Discharge I can't figure out why the final columns are displaying differently to all the others with exactly the same markup (extract below).
As you can see, adding "abbr=values" makes no difference at all. I want the displayed values to be 72.9 and 80.4

It's been too long since I've thought about
Module:Convert for me to have a definitive answer without significant thought and I won't have time for that until the weekend. The key problem is that the million for the input unit (e6t) comes from the default of the input not being abbreviated. However, the output (e6ST) is abbreviated and that gives the ugly exponent. The option to override that is abbr=unit which gives both input and output unit symbols but preserves multiples such as million. Demo:
{{convert|67.3|e6t|e6ST}} → 67.3 million tonnes (74.2×10^6 short tons)
{{convert|67.3|e6t|e6ST|abbr=unit}} → 67.3 million t (74.2 million short tons)
Problem: disp=table needs abbr=values to show the numbers only (abbr=values is the default for disp=table). I can't think of a workaround at the moment. In a few days I'll sit down and work out what's going on and might come up with a solution.

The heading says million for the output, so shouldn't the input be divided by a million too?
