 This file defines the torque converter characteristics as described in VDI 2153:
 
--   **Speed Ratio** (ν) = Output Speed / Input Speed
--   **Torque Ratio** (μ) = Output Torque / Input Torque
--   **Input Torque** (T~ref(ν)~) is the input torque (over ν) for a specific reference engine speed (see below).
+-   **Speed Ratio** ($\nu$) = Output Speed / Input Speed
+-   **Torque Ratio** ($\mu$) = Output Torque / Input Torque
+-   **Input Torque** ($T_{ref}(\nu)$) is the input torque (over ν) for a specific reference engine speed (see below).
 
 The Input Torque at  reference engine speed is needed to calculate the actual engine torque using this formula:
 
-$T_{in} = T_{ref}(v) \cdot ( \frac{n_{in}}{n_{ref}} )^{2}$
+$T_{in} = T_{ref}(\nu) \cdot ( \frac{n_{in}}{n_{ref}} )^{2}$
 
 $\mu(\nu) = \frac{T_{out}}{T_{in}}$
