If you prefer to use the part-way of calculating (as used in Polytek’s Deadener & Hardener for Platsil Gels Technical Bulletin) you can click here to pop up that calculator.
If you want to know more about the system of gels, you can read the Platsil Gels Technical Bulletin.
You can use this calculator to figure out the mixing ratio of silicone based on the total amount needed and the softness needed for a project.
The amount of A and B is greyed out since this the silicones this calculator is used for always use a 1:1 mix ratio. If you use a silicone with another mixing ratio, use the Mix Ratio General instead.
A: g
B: g
Deadner: g
(Mixing ratio: )
A: g
B: g
Deadner: g
(Softness: %)

How much silicone need to fill or make your item/mould/thing.
You need to figure out how soft (or, for that matter hard) silicone you need in a % of A and B.
This can be noted as a % of the silicone (A + B) or as a part of the total (as 1A:1B:?D)
You always have 50/50 of A and B.
Deadner (or Hardener) is in addition to this.
The calculation finds a ratio, and this ratio is multiplied with the amount of A, B and D.
