No.

These are made for daylight color film to look white under tungsten lighting. Tungsten light is much more yellow than daylight, which is quite blue (5600° K +), therefore you add a bit of blue in this filter to balance it to what the film is designed for.

The effect with black and white would be completely negligible. Contrast filters are used for B&W film; like yellow, orange, red, green or blue. All of these are quite saturated filters.

Ahh, it just occurred to me that B+W probably threw you off... that is the name of the company.

What is the most important filter for Color Conversion when I shoot with color film

For Black and White, I often use light yellow and yellow filters when photographing outdoors. These are useful for removing blue from the sky, and therefore making clouds visible in the final image. More information on black and white filtering:http://www.acecam.com/magazine/filters-faq.html

For color, I commonly use warming and sometimes cooling filters. Of those, 81A is my most commonly used filter. These are only for effect, not for "color conversion". In other words, I want the scene to appear more yellow or more blue so I use a filter.

What he said. 81A is great for warming up a cold/bluish day. Perfect on ski-slopes, that kind of thing. Technically it is a color "balancing" filter, I believe. But these terms are arbitrary.

It's good to have 81A, B, C, etc. for varying degrees, and then the bluish version, though I think I would find less utility in making a scene bluer. A set of decamired filters would be great, but I've never seen a threaded set, just "Series" sizes, which are a kind of old school filter scheme.

What are you shooting? Slides or negs? Are you printing in a darkroom, or scanning, or projecting? If you're scanning (dare I say), all these light balancing effects can be achieved in post for the most part. Projection would be where these filters are most important, and I'm honestly not familiar with the level of control in RA-4 or Cibachrome printing to say if the filters make it a lot easier to get the look you're going for.
