Not sure what I'm about to mention is a bug or it's just me missing something but I noticed selecting/changing some of the fiat currencies, leads to a slight change in all of the input fields in the right section ^{[bitcoin, bitcent and etc...]}.

• Default ^[before]
• After selecting BRL

Thank you for your comment, just fixed.


This is a limitation of the tool. I can "fix" by reducing precision. Just did (You probably won't see changes for a few minutes due to caching.)

The API I use only works with 2 decimal places. But USD BRL is not just 5.46, but 5.4587698 (something like that).
When you multiply 5.46 * 16000 those subcents units make that difference. I forced bitcoin field to 6 units instead of 8 and it is now 1.
It looks better now (1 BTC), but when you go to smaller units like uBTC you get  1000000.08.

Edit: I changed to another API with better precision. Workibng slightly better

Thanks your comment.


I know. But I only have this one for now

Do you think it would be better to keep those pages in separate domains? Like bitcoinunitconverter.com ?
Thank you, I am having a lot of fun and learning a lot working in this domain.

1 satoshi is 1000 millisatoshi. At the moment it says 10.

Using the arrow keys to navigate up and down the menu of fiat currencies is out by one. For example, if I click on Czech Koruna (CZK) and type in 100, I get a USD value of around $4.50. If I then press down to Danish Krone (DKK), it still shows the exchange rate for CZK. If I press down again to go to Euro (EUR), if then shows the exchange rate for DKK at $15.90. Similarly, if you scroll up you end up out of sync by one in the other direction. A minor point, but could cause some confusion.

Good catch!! Fixed!!


Fixed (Just disabled those arrows  

I agree. I want to see how it goes.

For example, if my mempool pages gets lots of access, I can create a yourtxinthemempool.com or something like that. Or btcunitconverter.com

but for now, I have so little traffic that it is not worth and it would be too much work.


Yeah, but I couldn't keep it updated. You can still access using the URL https://bitcoindata.science/supertable.html
I am learning more about API and databases, maybe in the future I can keep it automatically updated and I will put it back online.

Thank you


Thanks. That was a good idea.

I could reproduce by using the keyboard only.
I think it is much better now. Thanks

I have to admit that until now I didn’t even know there was a unit named after Hal Finney, and I’m just glad it existed because he totally deserved it.

I personally like how the site is designed and I think it can be very useful to anyone who wants to see how much BTC is actually worth in its local currency. I also like the part where you can check the current state of mempool, and see where we can expect our transaction to be positioned considering the fee - maybe just to mark more than 3 blocks on the graphic display, so that even those inexperienced users know what awaits them if they pay a fee 1 sat/vbyte.

This is a copy-paste from https://en.bitcoin.it/wiki/Units
I decided not to mention all those formats, because most of them are not used anymore. Even cBTC is not used anymore as it is too much money already...

Additionally, Tonal Bitcoin (which is almost half of that table) is basically an altcoin within bitcoin blockchain and it not support by any relevant client.

Edit: Its representation is not supported by any relevant client.

This was a design choice.

I have to keep something fixed and change the other values for that to work. There must be some reference value. I choose to use BTC as a reference.

When you change the currency the BTC value is fixed and the the currency price you select is what changes.

The other option would be to keep the fiat value and change bitcoin.
For example, 18,000 USD is one bitcoin. But one Bitcoin in AUD is 24900

If I changed the BTC value, it would convert 1 BTC to 0.68. (looks ok)

But if you change to VES (Venezuela Bolivar) that would be only 0.00000175.

Do you think it would be better to do this way? I can easily change to that design.


Edit: The difference 0.999998btc or 1.0000001 btc is due to very small differences in currency prices. For example, USD/BRL is not 5,3357 but it has a few more decimals. When you multiply that for big numbers (like btc price ) it makes very small differences. I tried to reduce precision but it would bug small values. I will try again to fix it.

I liked this idea. I will make a 1 BTC and 1 mBTC  button. Do you have more suggestion about btc values?


Every 20 seconds.


Thanks. I am satisfied with exchange.host
It supports 170 currencies (I added just about 40 because the dropdown would be too big, it would damage navigation). If you miss important currencies, let me know. I can just add them to the dropdown list.

Almost perfect timing, sicne preev has recently gone down, could see a momentum shift in the amount of visitor especially if preev isn't back online within a few days. Personally, and I know this isn't that bad, but the domain choice seems quite long to type out, since I tend to avoid using Bookmarks. That would probably be the only criticism without extensive testing to see if there's any kinks, but the interface seems decent to me so far.  

I like the suggestion, but isn't there a few currencies which use the same sign? Like Canadian dollars, uses the same sign as American Dollars? I think most people that speak different languages are familiar with the abbreviations of each countries currency, even if they don't speak English, because of its dominance in the world, and being dubbed the language of the internet a few times, its fairgly common for people to know USD, GBP even if they aren't familiar with the language.
