Could we work backwards from the C values to get the actual F values?

I don't want to allow more decimal places in the data than are valid,
and I've a feeling that the extra decimal places come from the F data
conversion to C.
There could be all sorts of crazy rules that describe when extra
decimal places are allowed and when not depending on when the
temp was read in F and when in C, but that seems silly
when we could just record the original data.
