You really can't for a few reasons:
- The amount value isn't an absolute, but varies with the camera. In general (there are exceptions), a camera with a weak AA filter will get less sharpening than one with a strong filter, even though both are set to the same value.
- The Detail and Masking parameters don't exist with NX2. The former governs halo suppression and also moves the sharpening toward deconvolution sharpening as you go higher in the value. The latter adapts the sharpening more toward what you are used to with high-pass sharpening as you go higher in value. Lower amounts just suppress sharpening from areas lacking detail. To a certain extent, higher Detail settings align with situations where you'd use a very low threshold amount in NX2 and higher masking amounts align with situations where you would use a higher threshold (like noisy shots), but they're really different things.
I usually find myself using amounts in the 35-60 range, radii in the 0.6 through 1.3 range, detail settings in the 15 through 50 range and masking from 0 to 60 or 70. If you have a specific setting in NX2 that you like with a given camera, let me know and I'll give you a suggestion for a very rough equivalent.

It's good for getting a lot of detail out of blurred images - reading license plates that are a bit blurred out. is a good example It can be quite strong, so you have to be a bit careful using high amounts of detail. For certain subjects where you have a lot of detail that you want to see and the ISO is relatively low, it can work.

I never think of the values but the results. I start with Masking, with Alt key held down, so that I can see a sharpening mask. Only the white areas are sharpened. With a tight mask, it is possible to drag the Intensity to 100% and beyond, if the object is sharply-defined. With 12 – 18mp sensors, the Radius is typically around 1, with the 36mp sensor of the D800E, the radius can be higher, about 1.5 or 2, because the pixels will not be enlarged as much as they are from sensor with fewer megapixels. I only touch the Details if the result looks unsatisfactory, usually with the Alt key held down so that I can see the effects of the adjustment.
Traditional wisdom says that sharpening should be done at 1:1 preview because 1:1 used to be the only magnification ratio at which Adobe products could approximate the ultimate output. With newer Adobe software and cameras with more megapixels (the D800E), it is possible to sharpen at 1:2, provided that the photos is not significantly cropped. Again, because individual pixels will not be blown up as much as they are with 12 – 18mp sensors, it makes sense to evaluate sharpening at lower magnification.
Amount, Radius and Masking in LR map to Intensity, Radius and Threshold in CNX2. Amount/Intensity and Radius increase the sharpening effect, Masking/Threshold chokes it. Detail lessens the choking effect near sharp edges.

The new Photoshop CC Smart Sharpen has improved a great deal but with all PS sharpening you always always change the blend mode to luminosity because it's the only thing that needs sharpening. The new ability to make is a smart object lets it be nondestructive and you can come back and crank it up more. If you don't change the blend mode you start losing it quicker. I find I don't add much in LR but just a little before printing helps you see the image better in post.
