How to mark or calibrate the scales:
To do this, you will need some accurate standard weights. Perhaps you can . . .
borrow some weights from
a merchant at the market
or use his scale to prepare
several and weights
or borrow some 1-kilo
packages or cans of food.
To mark your scale:
1. Hang 2 kilos on it.
2. Balance the
movable weight
3. Mark the spot
with a small line
and write a ‘2’.
4. Now add one more kilo
and repeat the process.
Keep going until the
whole scale is marked.
To weigh children up to
age 5, mark your scale
up to 20 kilos.
