<p>So, I have looked everywhere and no one seems to have this specific problem. </p>

<p>I have set up a e-commerce store that is accepting BTC, So far the users can only see the price of the product in USD, however, I want the user to be able to click the USD price and convert it to BTC instantly. Like you can on a blockchain.info transaction.</p>

<p>For example:</p>

<p><a href="https://i.sstatic.net/gRPY4.png" rel="nofollow noreferrer">Blockchain transaction conversion</a></p>

<p>So far, I have only been able to display the BTC price using Blockchain API.</p>

<p><strong>I want the same effect as Blockchain on my price, or atleast under it.</strong> </p>

<p><strong>(Snapshots of site below to give an idea of what I want)</strong></p>

<p>The code I have to display the BTC price (If it helps, im a noob sorry)</p>

<pre><code>&lt;?php

  $url = "https://blockchain.info/stats?format=json";
  $stats = json_decode(file_get_contents($url), true);

  echo $stats['market_price_usd'];

  ?&gt;
</code></pre>

<p>Price display:</p>

<pre><code>&lt;p class="Price"&gt;$200.50&lt;/p&gt;
</code></pre>

# USD to BTC conversion code

(Asked by: username_0 on 2016-08-30)

So, I have looked everywhere and no one seems to have this specific problem.

I have set up a e-commerce store that is accepting BTC, So far the users can only see the price of the product in USD, however, I want the user to be able to click the USD price and convert it to BTC instantly. Like you can on a blockchain.info transaction.

For example:

[Blockchain transaction conversion](https://i.sstatic.net/gRPY4.png)

So far, I have only been able to display the BTC price using Blockchain API.

**I want the same effect as Blockchain on my price, or atleast under it.**

**(Snapshots of site below to give an idea of what I want)**

[My images](https://i.sstatic.net/pmyD7.png)

The code I have to display the BTC price (If it helps, im a noob sorry)

```
<?php

  $url = "https://blockchain.info/stats?format=json";
  $stats = json_decode(file_get_contents($url), true);

  echo $stats['market_price_usd'];

  ?>

```

Price display:

```
<p class="Price">$200.50</p>

```

Your question is a bit confusing but it sounds like you are asking how to get a currency amount worth of bitcoin.

> I want the user to be able to click the USD price and convert it to BTC instantly.

The answer is simple, division.

```
<?php
$url = "https://blockchain.info/stats?format=json";
$stats = json_decode(file_get_contents($url), true);
$btcValue = $stats['market_price_usd'];
$usdCost = 200;

$convertedCost = $usdCost / $btcValue;

echo $convertedCost;
?>     

```
