Read dial scales, step by step

A kitchen dial turns weight into an angle.

The question

Read the dial

goes up to:1000g

gaps:10

one gap:100g

look straight on

100g per gap

gaps counted:6

count in 100s:100, 200, 300, 400, 500, 600

Work out one gap before anything else. The dial reads round to 1000g, shared over 10 equal gaps — so one gap is 100g. Not one — that is the assumption this whole topic is built to break.
Read where the needle points, straight on — looking at a dial from the side moves the needle by a mark or two.
Count the gaps up to it: 6. Now count those gaps in 100s — 100, 200, 300, 400, 500, 600 — so it reads 600g. Counting the marks alone would have given 6, which is the wrong answer that looks right.

How it works.

01
Work out one gap before anything else. The dial reads round to 1000g, shared over 10 equal gaps — so one gap is 100g. Not one — that is the assumption this whole topic is built to break.
02
Read where the needle points, straight on — looking at a dial from the side moves the needle by a mark or two.
03
Count the gaps up to it: 6. Now count those gaps in 100s — 100, 200, 300, 400, 500, 600 — so it reads 600g. Counting the marks alone would have given 6, which is the wrong answer that looks right.
