85 g to kg

85 g = 0.085 kg

Divide the gram value by 1,000 — the prefix kilo- means exactly one thousand. So 85 g ÷ 1,000 = 0.085 kg.

Multiply by 1,000, the inverse operation: 0.085 kg × 1,000 = 85 g. Converting in both directions is the quickest check that the figure is right.

Because kilo- stands for 10³, so one kilogram holds 1,000 grams. Moving the point by one or two places instead is the usual slip and makes the answer 100 or 10 times too large.
