Units
For futures, the units are displayed like this:
(UnitNumeratorMultiplier) CurrencyCode / (UnitDenominatorMultiplier) UnitDenominatorTypeId
For example, for #2 Live Cattle,
Units = 0.01 USD / 1 lb
(In other words, cents/lb)
For #65 Japanese Yen
Units = 1 USD / 100 JPY
Contract Value
The Contract Value = Contract Size x Price
For #2 Live Cattle,
Contract Value = 40000 (lb) x 105 (cents/lb) = 4,200,000 cents = $42,000 USD
FullPointValue x Price also works. This is because FullPointValue is always in terms of the whole currency instead of cents.
Contract Value = 400 x 105 = $42,000 USD
