Conversion (conversion)

Performs an arithmetic conversion of an existing parameter.

Field	Description	Required
parameter	Name of the new parameter to be included in the param column of the output file	✅ Yes
paramcd	Parameter code for the new parameter to be included in the paramcd column of the output file. Only alphanumeric characters and underscore (_) are allowed.	✅ Yes
uniqueId	Unique ID variable in the input file.	✅ Yes
units	Units of the new parameter	✅ Yes
paramcd	Parameter code for the original parameter to be converted.	✅ Yes
column	Column of input file for condition matching.	✅ Yes
value	Value of column to be matched for data filtering (if under term1 - conditions), or value for conversion factor (if under term2)	✅ Yes
operator	Arithmetic operator for conversion. Accepted values are +, -, *, and /	✅ Yes

Tip

All conversions are calculated as follows:

• new parameter = [term1] [operator] [term2]
• where [term1] is a parameter from the input file and [term2] is a conversion factor

If you need to perform a calculation such as 1 - [parameter], use the addition operator and a negative value for [term2].

Example:

{
  "description": "Conversion Calculation Description",
  "version": "3.0.0",
  "parameter": "Apparent Clearance (linear) in liters/hr",
  "paramcd": "CL_f_lin_liter",
  "uniqueId": "subject",
  "units": "L/hr",
  "term1": {
    "paramcd": "CL_f_lin",
    "conditions": [
      {
        "column": "day",
        "value": "Day 1"
      }
    ]
  },
  "operator": "/",
  "term2": {
    "value": 1000
  },
  "type": "conversion"
}

Behavior: Creates a new parameter named Apparent Clearance (linear) in liters/hr using the following equation: new parameter = CL_f_lin / 1000.
