Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`double`	`fromStandardUnit(double value)`	Convert a value from an SI value to a value in the unit that uses this scale.
`boolean`	`isBaseSIScale()`	Return whether a scale is a 'standard' scale that would belong to an SI unit.
`double`	`toStandardUnit(double value)`	Convert a value to an SI value using this scale.

- Method Detail
  - toStandardUnit
```
double toStandardUnit(double value)
```
    Convert a value to an SI value using this scale.
    
    Parameters:
    
    value - double; the value to convert
    
    Returns:
    
    the corresponding SI value
  - fromStandardUnit
```
double fromStandardUnit(double value)
```
    Convert a value from an SI value to a value in the unit that uses this scale.
    
    Parameters:
    
    value - double; the value to convert
    
    Returns:
    
    the corresponding value in the given unit
  - isBaseSIScale
```
boolean isBaseSIScale()
```
    Return whether a scale is a 'standard' scale that would belong to an SI unit. For a linear scale, any scale with conversion factor 1 would be considered standard. For an offset scale, it would be considered standard if the offset is 0 and the conversion factor is 1.
    
    Returns:
    
    boolean; whether the scale is a 'standard' scale that would belong to an SI unit.
