103 545.34 m³ (NOV) or 102 345.34 m³ (NSV) are quantity values for the quantities net observed volume (NOV) and net standard volume (NSV). Quantity values are typically determined by a measurement or a subsequent quantity conversion from a quantity value obtained by measurement.
You multiply a quantity value with the price per unit of measure for that product to obtain the total value of the product.
Diesel is e.g. priced at 500 € / ( m³ at 15 °C )
- m³ is here the net standard volume (NSV) – specification of the quantity (and standard temperature) is important.
You multiply: 102 345.34 m³ × 500 € / m³ = 51 172 670 €, which is the value of your product.
Since volumes change with temperature and pressure, it is important to convert the m³ quantity value from an observed volume to a m³ quantity value for a volume at a defined reference temperature and reference pressure.
