Why should a site like this possibly need to be potentially sharing data with one and a half thousand other entities?

My personal favourite unit converter is here: https://www.theregister.com/Design/page/reg-standards-conver...

Looks nice and useful!

One minor feedback would be - you could move the "Browse related converters" section to the right panel which is empty now.

[rpcom]

Makes sense - to fill UI voids. Thank you for the feedback.

Has the same problem with time as I see elsewhere. I don't don't want to convert a billion seconds to number of hours and then days and then weeks and months and then years. I want to translate that to a human readable years/months/days/hours/minutes/seconds in one click.

The red under "Free Online" looks weird to my eyes, like it was half crossed out with a red highlighter.

The helpful descriptions under the conversion doesn't seem to switch to the ones you have selected. I expected when I switched the time from minutes to years, the box would have defined years.

Thank you for the feedback.

Usually users search a specific unit conversion, such as “convert meters to feet”. They will be redirected by a search engine to a dedicated page with detailed units descriptions down below the category page, example https://www.betaconvert.com/length/meters/feet , do their conversion and leave. For the case when a user begins navigation from top-bottom, we will consider to load a proper unit description on unit change as you have suggested.

I often need a quick and easy conversion tool for mapping a val from one range to another

Also have a hard time finding good resolution/aspect ratio calculators

Finally the most fraught online calculator tooling I know of is projector throw distance and part specs calculators/visualizers

I'm generally content with ddg converter, the only its issue it is hard to convert pounds into a metric units, because ddg stubbornly believes that the pound is a currency. It will happily convert pounds into dollars, but not into kilograms.

Hi - do you have an example query showing this issue? I just tried "45 lb to kg" on DuckDuckGo and it's working as I would expect (45 Pounds = 20.41166 Kilograms).

I find natural language much easier, it's one single interface-- I just use raycast. If I type "20ft" it defaults showing in meters, so I don't even have to type anything extra, it's great

[ishtanbul]

the color scheme is low contrast. i would recommend black and white instead

[rpcom]

This is important suggestion that we should consider for better usability. Thanks.

We are near “Moores law” limit for how simple a unit converter can get

[janalsncm]

Here is my feedback:

1. You don’t need an internet connection for simple unit conversion.

2. You don’t need to share data with 1400+ spy tech organizations. You don’t need cookies at all. It’s a stateless calculator.

[smusamashah]

Additionally, this being simplest I wasn't expecting a new page for every category of unit and the added load time with that.

We use high-precision calculations up to 28 decimal digits that cannot be provided by numeric types available in Javascript. That’s why we do our calculations on the backend.
