\title{Canonical SoilGrids 250m unit-conversion factor per property}
\usage{
.soilgrids_scale(property)
}
\arguments{
\item{property}{One of the SoilGrids properties.}
}
\value{
Numeric scalar. The native integer value times this scale
        yields the conventional unit:
\itemize{
  \item clay/sand/silt -- 0.1 (g/kg integer -> percent)
  \item phh2o          -- 0.1 (pH * 10 integer -> pH)
  \item soc            -- 0.1 (dg/kg integer -> g/kg)
  \item bdod           -- 0.01 (cg/cm^3 integer -> g/cm^3)
  \item cec            -- 0.1 (mmol(c)/kg integer -> cmol(c)/kg)
  \item nitrogen       -- 0.01 (cg/kg integer -> g/kg)
  \item ocd            -- 0.1 (hg/m^3 integer -> kg/m^3)
  \item ocs            -- 0.1 (hg/m^2 integer -> kg/m^2)
  \item cfvo           -- 0.1 (cm^3/dm^3 integer -> percent vol)
}
}
\description{
SoilGrids stores integer rasters; the published conversion factors
are documented in \emph{Hengl et al. (2017)} and the SoilGrids
README. This internal lookup table applies the right factor so
\code{\link{lookup_soilgrids}} returns conventional units.
