Fourth calculator from the top, set to Percentage.

In this example you would combine 875 ml of water with 125 ml of 32% HCL to get one liter of 4% HCL. Be sure to add the acid to the water and not the reverse. The solution will become warm.

The calculator link you provide is offline. Here's another that works well.

3ml acid +27ml water = 30ml 4%

Thought I'd put this warning here, regarding the concentration of HCl 37%

When creating Hydrochloric Acid Solution 4% (from hydrochloric acid 37% and distilled water) use caution.
Concentrated HCl is a very strong acid that will burn skin instantly upon contact!
Wear gloves, goggles, and lab coat.
The acid MUST BE ADDED TO THE water (not the reverse)! Otherwise, the drops of water mixing with the concentrated acid will heat up, evaporate, and potentially spew acid from the container.
