OUTCOME
Make one dated comparison of two market quotes, a cost estimate for something
you grow, raise or make, and one useful question for the seller or maker.

1. RECORD THE SAME THING
Name the product, quality, date, currency and stage of sale. A raw commodity,
a local food product and a finished handmade object are different things.
World Bank figures in this edition are September 2026 monthly averages,
published October 2; they are not live local prices. Retail examples are
individual asking prices checked October 5, not typical prices or appraisals.

2. CONVERT THE BUNDLE
Price / quantity in a common unit = unit price.
1 metric tonne = 1,000 kg. 1 lb = 0.45359237 kg.
1 ordinary ounce = 0.028349523125 kg. A troy ounce is a different unit.
1 dozen = 12 pieces. A piece, basket, egg or pint has no fixed mass here.
To compare a counted item with a weighed item, weigh the counted item first.
Watch the scale start at zero. Use net product weight, excluding packaging.

3. COUNT WHAT YOU CAN USE
Usable amount = gross amount x usable percentage / 100.
Price / usable amount = cost per usable unit.
At zero output or zero usable share there is no cost-per-unit estimate.
Ask about freshness, breakage, storage, transport and the quantity you need.
Cheaper per kg can still be unaffordable as a bundle or go to waste.

4. COUNT THE WORK TOO
Batch cost = inputs + other costs + (hours x chosen hourly pay).
Cost per usable unit = batch cost / usable output.
Count seed/feed/yarn, energy, water, packaging, equipment allocation,
travel and selling costs for the same production period. Keep cash costs
and the allowance for your own time separate. The worksheet excludes
profit and costs you have not entered. A calculated cost does not establish
what a customer will pay. Record losses instead of assuming perfect yield.
For home-raised livestock, live, carcass and edible weights are different;
compare the same stage and use your measured yield.

5. RESPECT THE CRAFT
A finished dress or shawl sells per piece. Price / its measured finished kg
is a ratio, not raw wool/cotton value. Handwork, preparation, design,
finishing, distribution and reputation can contribute to the asking price.
Do not infer a maker's wage from a shop price. The Heron dress has no
published weight, so the exercise keeps that weight unknown.

OPTIONAL CURRENCY STEP
Use local currency units per 1 USD. Local price / that rate = USD price.
Record the rate source and date. Actual exchange fees can change what you
receive. No rates or accounts are fetched by this lesson.

YOUR RESULT
Open index.html, replace the practice inputs, answer the three questions,
and save your market note. The note records inputs, dates and unknowns.
The page stores entries only in memory; refreshing clears them. Printing
or saving is your choice. No account, payment, model or external feed.
