## Options

### Solve for

The standard density calculation methods are bi directional

- Standard density

Calculate the standard density from the density at a given pressure and temperature

- Density

Calculate the density at a given pressure and temperature from the standard density

### Standard Temperature

- 15°C

- 60°C

This option allows selection of standard temperature.

### Commodity Group

- Crude Oil

- Fuel Oils

- Jet Fuels

- Transition Zone

- Gasoline

- Lubricating Oil

- Other

Select appropriate commodity so that the correct K values are used in the calculation. They are needed to calculate the thermal expansion factor of the liquid.

If the last option, other, is selected then you will have to input the relevant K values.

### Precision

The precision options enables switching between rounding methods

- Full

This enables you to bypass the rounding methods outlined in the algorithms and use the full precision during the calculation

- Rounding

Select this option to follow the algorithms to the in the standard

## Calculations

### Cpl

The correction for pressure is calculated using the Institute of Petroleum Paper 2 calculation(see C223).

### Ctl

The correction for temperature is calculated using the calculation from API MPMS Chapter 11.1 (see C222).
