Under SM: P VM A-2.4 Select Special Ordnance (11) p. 110 I believe there is an issue with the Total Vol. of Ordnance calculation and/or the Mass shown in the Ordnance Table VM-10.1.
The Ordnance Table VM-10.1 shown on p. 110 appears to have been copied from the table on p. 60 and had the third column change from Weight in kg, text p. 60, to mass in metric tons.
The weight for the Ultra-Compact Autocannon TL 14 500 kg per Table VM-10.1 on p. 60. Table VM-10.1 on p. 110 shows the same weapon with a mass of 500, which in A.2-4 is measured in metric tons.
Following the Total Vol. of Ordnance calculation of (Mass in metric tons) x 1 a Ultra-Compact Autocannon TL 14 weapon has a volume of 500 x 1 = 500 kiloliters.
A 500 kg piece of equipment would have a mass of 0.5 metric tons not 500 metric tons.
Two recommendations appear to correct the volume calculation in Select Special Ordnance (11) p. 110
Recommendation 1: Do a pen an ink change to the Total Vol. of Ordnance and Total Mass of Ordnance calculation p. 110.
Change the calculation from (Mass in metric tons) x 1 to (Mass in metric tons) x 0.001
Change Total Mass of Ordnance: see below to Total Mass of Ordnance: (Mass from table below) x 0.001
Recommendation 2: Do a pen an ink change to each numerical value under the Mass column header.
Convert the listed numbers from kg to metric ton by using the formula kg ÷ 1,000 or kg x 0.001.
Being kind of lazy I'd change the formulas
