Linear interpolation error

I have two set of data for pressure and energy density and I used a linear interpolation to apply the data as a function in terms of each other. Interpolation[Most@Transpose[{Pressure, EnergyDensity}], InterpolationOrder -> 1]; fromEnergyToPressure = Interpolation[Most@Transpose[{EnergyDensity, Pressure}], InterpolationOrder -> 1]; Then for some cases, I faced the error below. InterpolatingFunction::dprec: The precision of input value {3.60289*10^16} and/or the interpolation grid is insufficient to compute the value. Could you please help me that how I can solve this problem.

fromEnergyToPressure =

Is there any problem that I also posted my question on another site?

No, there is no problem. But mentioning that same question was asked somewhere else helps the members here to check what answers and suggestions you already got before trying to help you. This also prevents redundant answers and wasted efforts.
