We give the conversion equations which lead from experimental values of the 3p → 1s transition energy in pionic hydrogen and the total width of the 1s level to values of the s-wave threshold scattering parameters for the processes π -p → π -p and π -p → π 0 n respectively. Using a three-channel pote
