Analyze the scale of the objects

Flowers and leaves are very light objects, typically weighing a fraction of an ounce or a few grams.

Compare the given units of mass

• Tons and kilograms are used for very heavy or large objects (e.g., vehicles, bulk cargo, human body weight).
• Pounds are used for medium-weight everyday items (e.g., groceries, packages).
• Grams are the standard metric unit for small, lightweight objects, making measurements of plant parts easiest to read without using tiny decimals.

Select the most appropriate unit

Grams provide the most practical and readable scale for weighing individual flowers or leaves.
