A true zero point is the feature of

A scale is a tool or something that is used to gauge or quantify a situation or something else.

Key Points

• Measuring scales are used to define and categorize variables. 
• There are four different scales of measurement Ordinal scale, Nominal scale, Interval scale and Ratio scale. 
• Ratio scales have all four scales of measurement represented by attributes. 
• The ratio scale allows for the addition, subtraction, division, and multiplication of data.
• Ratio scales have a real zero point which sets them apart from interval scales.
• The data has no value point if the number is 0.

Thus, A true zero point is the feature of the Ratio scale. 

Additional Information

• Nominal scale: The identity property of data. 
• Interval scale: The characteristics of nominal and ordered data are present in the interval scale. 
• Ordinal scale: Data is placed in a particular order.
