Actually you can't make a straight volume-to-weight conversion like this as it depends first of all on the units of measurement and then on the density of the measured product. What you posted there simply looks like the standard volume of one US customary cup (which is precisely 236.58824 mL).
The general desity of lard as I have found has been set to 216.62 grams per metric cup (250 mL). So that would mean that lard has a density of 0.86648 gram per mL. Note that the density value may change from one source to another. Another one I found said 0.772 g/cm3 (which is quite diffrent) so I'll do both conversions for the sake of it. Average density from both value is of 0.819 g/mL.
So here are the approximate results considering those values. The diffrences in density values may be explained by the lard's composition, the way it was measured/determined and the lard's phase (either solid of liquid). Unfortunately, I don't have these informations (especially if it's the solid or liquid density) in regards to the values I found (although it shouldn't make much of a diffrence for cooking purposes). So just take it as a mere approximation.
You'll have: volume = weight @ 0.86648 g/mL // weight @ 0.772 g/mL => average
- One metric cup (250mL) = 216.62g // 193g => 204.81g
- One US cup (236.6mL) = 205g // 182.66g => 193.83g
Hope it clarifies things a bit.
