It's probably region-specific. OP is in the UK, where the unit of currency is the Pound Sterling (or "pound," £), and most people measure mass in metric (kilograms). So Siri, right or wrong, is assuming that someone in the UK is talking about money when they say "pounds."

In the US, pounds refers to weight, and we'd probably be more likely to want to convert weight in pounds to mass in kg. So Siri parses the query correctly there.

Not to say it's being done right. Siri should've figured out that kilos refers to mass and then figured out what was meant that way.

EDIT: Well, so much for my theory. The opposite works fine in the US (pounds to US dollars). Must be a bug.

In the UK, people of a certain age ie those who learned their weights and measurements at school before 1971, still use ft, inches, miles, pounds etc.
in fact, all of our green grocers won the right to only use pre-decimal units on their signs.

I reckon Siri needs a big upgrade now that Cortana has come along too

"Siri, how many kilograms is 2.6 pounds".
Actually, no...

One should choose pounds-mass (LBM)/kilograms or pounds-force (LBF)/kilograms-force when making a "mass" or "weight" conversion.

Gravity is everywhere - the Queen is not, so I'm not getting into the difference between a US mass vs. an Imperial mass. If one wants to know the difference between mass and force, sit through a couple of years of physics like I did in the 80s.

"Convert 2.6 pounds force to kilograms."

Pounds is "pounds mass". Kilograms and pounds-force addresses "force" - or the gravitational pull of the Earth, called gravity - what you feel in your hand when you hold an object. Mass times gravity equals force.

Doesn't work in NZ; it detects it as "£2.6 in kilograms" and gives the "not compatible" message. Presumably it'll do the same in the UK.

There is no NZ option for Siri so it defaults to UK over here.

You typed lbs for pounds (measurement of weight) instead of speaking "pounds" into the phone, which is ambiguous as pointed out already.

where it says tap to edit. Edit it to say the right thing. Then next time you say it siri will know.

"Siri, how many kilograms is 2.6 pounds".

That works fine, but the whole point of Siri is not to have to type anything at all.

If I'd said "Two pounds sixty", I could understand, but in terms of currency, nobody says Two point six pounds" unless they mean weight.

Anyhow, I edited the input and it worked so then I asked again in the same way but she still assumed I meant currency, so didn't learn
