In the metric system, the Gram, as in kilogram is the standardfor mass measurement
The best estimate for a pair of sneakers is 1 kilogram.
It is okay to estimate mass when precise measurements are not required, or when the mass is difficult to measure accurately. Estimating mass may be acceptable in everyday situations such as cooking or packing luggage, but for more critical applications like pharmaceutical production or research, it is best to use precise measurements.
you can measure the mass by putting it on a balance and measure really quickly. the volume you can estimate an approximate answer by putting it in water and measuring its displacement.
Inferred mass measurement is a technique used to estimate the mass of an object or system based on indirect observations or related properties, rather than direct measurement. This approach often relies on principles from physics, such as gravitational interactions, dynamics, or statistical methods, to derive mass estimates. It is commonly applied in fields like astrophysics, where the mass of celestial bodies may be inferred from their gravitational effects on surrounding objects. Inferred mass measurements can provide valuable insights when direct mass measurement is impractical or impossible.
Which is the best estimate for the mass of a duck?

That depends a lot WHAT you want to estimate about the lemon - which of its qualities, e.g., its mass, its diameter, its sourness, its color, etc.
1 gram
15kg
About 250 grams
0.2 grams
1 gram
the nearest would be 15kg
