all pictures of big mac must be BIG!!!
I suggest not using that site as it doesn’t give a proper conversion. It uses a DPI/PPI on 96, even though the most common is 72. – But the actual density of every screen is different.
At first I used this converter.
Well, on my computer screen an exemplary 1000 pixels wide picture from this site is 27,65 centimeters wide (I checked it with a ruler).
So the picture of Big Mac will be 13,82 meters tall on my screen.
But yeah, there is not a standard size of a pixel.
Edited
That’s dependent on the pixel density.
And basing it off your values, you use a density of 37,8 px/cm, which is a higher density than the common default density of 28,35 px/cm.

A 1.5 gigapixel image, more specifically (1 464 800 000 pixels)
