A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement.

The quantity produced by the recipe (for example, number of people served, number of servings, etc).

The available volume for cargo or luggage. For automobiles, this is usually the trunk volume. Typical unit code(s): LTR for liters, FTQ for cubic foot/feet Note: You can use [minValue](https://schema.org/minValue) and [maxValue](https://schema.org/maxValue) to indicate ranges.

The amount of fuel consumed for traveling a particular distance or temporal duration with the given vehicle (e.g. liters per 100 km). - Note 1: There are unfortunately no standard unit codes for liters per 100 km. Use [unitText](https://schema.org/unitText) to indicate the unit of measurement, e.g. L/100 km. - Note 2: There are two ways of indicating the fuel consumption, [fuelConsumption](https://schema.org/fuelConsumption) (e.g. 8 liters per 100 km) and [fuelEfficiency](https://schema.org/fuelEfficiency) (e.g. 30 miles per gallon). They are reciprocal. - Note 3: Often, the absolute value is useful only when related to driving speed ("at 80 km/h") or usage pattern ("city traffic"). You can use [valueReference](https://schema.org/valueReference) to link the value for the fuel consumption to another value.

The distance traveled per unit of fuel used; most commonly miles per gallon (mpg) or kilometers per liter (km/L). - Note 1: There are unfortunately no standard unit codes for miles per gallon or kilometers per liter. Use [unitText](https://schema.org/unitText) to indicate the unit of measurement, e.g. mpg or km/L. - Note 2: There are two ways of indicating the fuel consumption, [fuelConsumption](https://schema.org/fuelConsumption) (e.g. 8 liters per 100 km) and [fuelEfficiency](https://schema.org/fuelEfficiency) (e.g. 30 miles per gallon). They are reciprocal. - Note 3: Often, the absolute value is useful only when related to driving speed ("at 80 km/h") or usage pattern ("city traffic"). You can use [valueReference](https://schema.org/valueReference) to link the value for the fuel economy to another value.

The total distance travelled by the particular vehicle since its initial production, as read from its odometer.<br/><br/> Typical unit code(s): KMT for kilometers, SMI for statute miles.

The number of axles.<br/><br/> Typical unit code(s): C62.

The total number of forward gears available for the transmission system of the vehicle.<br/><br/> Typical unit code(s): C62.

The number of owners of the vehicle, including the current one.<br/><br/> Typical unit code(s): C62.

The number of passengers that can be seated in the vehicle, both in terms of the physical space available, and in terms of limitations set by law.<br/><br/> Typical unit code(s): C62 for persons.

The duration of the warranty promise. Common unitCode values are ANN for year, MON for months, or DAY for days.

The number of doors.<br/><br/> Typical unit code(s): C62.

The annual rate that is charged for borrowing (or made by investing), expressed as a single percentage number that represents the actual yearly cost of funds over the term of a loan. This includes any fees or additional costs associated with the transaction.

The interest rate, charged or paid, applicable to the financial product. Note: This is different from the calculated annualPercentageRate.

The duration of the loan or credit agreement.

The reference quantity for which a certain price applies, e.g. 1 EUR per 4 kWh of electricity. This property is a replacement for unitOfMeasurement for the advanced cases where the price does not relate to a standard unit.

The size of the accommodation, e.g. in square meter or squarefoot. Typical unit code(s): MTK for square meter, FTK for square foot, or YDK for square yard.

The number of rooms (excluding bathrooms and closets) of the accommodation or lodging business. Typical unit code(s): ROM for room or C62 for no unit. The type of room can be put in the unitText property of the QuantitativeValue.

The allowed total occupancy for the accommodation in persons (including infants etc). For individual accommodations, this is not necessarily the legal maximum but defines the permitted usage as per the contractual agreement (e.g. a double room used by a single person). Typical unit code(s): C62 for person.

The frequency in MHz for a particular broadcast.

The time needed to accelerate the vehicle from a given start velocity to a given target velocity. Typical unit code(s): SEC for seconds - Note: There are unfortunately no standard unit codes for seconds/0..100 km/h or seconds/0..60 mph. Simply use "SEC" for seconds and indicate the velocities in the [name](https://schema.org/name) of the [QuantitativeValue](https://schema.org/QuantitativeValue), or use [valueReference](https://schema.org/valueReference) with a [QuantitativeValue](https://schema.org/QuantitativeValue) of 0..60 mph or 0..100 km/h to specify the reference speeds.

The capacity of the fuel tank or in the case of electric cars, the battery. If there are multiple components for storage, this should indicate the total of all storage of the same type.<br/><br/> Typical unit code(s): LTR for liters, GLL of US gallons, GLI for UK / imperial gallons, AMH for ampere-hours (for electrical vehicles).

The permitted weight of passengers and cargo, EXCLUDING the weight of the empty vehicle. Typical unit code(s): KGM for kilogram, LBR for pound - Note 1: Many databases specify the permitted TOTAL weight instead, which is the sum of [weight](https://schema.org/weight) and [payload](https://schema.org/payload) - Note 2: You can indicate additional information in the [name](https://schema.org/name) of the [QuantitativeValue](https://schema.org/QuantitativeValue) node. - Note 3: You may also link to a [QualitativeValue](https://schema.org/QualitativeValue) node that provides additional information using [valueReference](https://schema.org/valueReference). - Note 4: Note that you can use [minValue](https://schema.org/minValue) and [maxValue](https://schema.org/maxValue) to indicate ranges.

The permitted total weight of cargo and installations (e.g. a roof rack) on top of the vehicle. Typical unit code(s): KGM for kilogram, LBR for pound - Note 1: You can indicate additional information in the [name](https://schema.org/name) of the [QuantitativeValue](https://schema.org/QuantitativeValue) node. - Note 2: You may also link to a [QualitativeValue](https://schema.org/QualitativeValue) node that provides additional information using [valueReference](https://schema.org/valueReference) - Note 3: Note that you can use [minValue](https://schema.org/minValue) and [maxValue](https://schema.org/maxValue) to indicate ranges.
