Ade7763 on the voltage and current calculation

As the title, I get 0x16, 0x17, 0x22, 0x24 Vrms, Irms, VPEAK, IPEAK these 24Bit value, I want to convert to the real world values.
Through the following four lines
1. Apply a known current to the current channel.
2. Read the rms register and note the value.
3. Determine the amps / LSB constant: it is the ratio of applied Current to the rms register reading.
4. Store this constant in the microcontroller.
Convert all readings to real world values.
I know that through the amps / LSB, volts / LSB ratio to calculate, but the numerator and denominator to placed what?
The denominator  is placed the 1868467 = max value of the rms current (data sheet) 、1561400 = max value of effective stress (data sheet) .  
But the numerator to placed what? After the calculation?

Please help me.
