The answer depends on the distribution of the data - in particular, its skewness and the presence of outliers.
Grain is usually sold by weight or mass. An appropriate measure of volume would be the liter, but it is rarely used. A few countries use bushels.Grain is usually sold by weight or mass.

The appropriate metric unit to measure the mass of a lawn mower would be kilograms (kg). This unit is commonly used for measuring the weight of objects in metric system.
A gram would be an appropriate measure for its mass.
By unit of length and distance and conversion ,we can say that the most appropriate unit to measure the length of a finger is cm.
It is the mode.
Thermometer is the instrument used to measure average thermal energy.
No, measuring a sofa in grams is not appropriate as grams are used to measure weight, not dimensions. It would be more appropriate to measure a sofa in inches or centimeters to determine its size.
Liters is the appropriate unit. Milliliter can also be used.
Not sure what an instermant is, but an appropriate instrument is a protractor.

Either can be used for symmetrical distributions. For skewed data, the median may be more a appropriate measure of the central tendency - the "average".
A thermometer is generally used to measure the average kinetic energy of the molecules in a substance. The temperature reading on the thermometer is a reflection of the average kinetic energy of the molecules in the substance.
