Kilograms ➝ Ounces: Exact vs Practical
1. Core Formula
oz = kg × 35.27396195 (exact, avoirdupois). Use 35.274 for 3–5 sig figs. Reverse: kg = oz ÷ 35.27396195.
2. Flow
- Take kilograms input.
- Multiply by 35.27396195 (keep precision internally).
- Round display (2–3 decimals typical for kitchen).
- Show related pounds / grams for cross-check.
3. Sanity Checks
- 1 kg ≈ 35.274 oz
- 0.5 kg ≈ 17.637 oz
- 2 kg ≈ 70.548 oz
- 2.5 kg ≈ 88.186 oz
- 5 kg ≈ 176.37 oz
4. Shortcuts
- Rule of thumb: kg × 35¼ (35.25) → slight under.
- Fast mental: kg × 35 + kg × 0.27.
- Via pounds: kg × 2.20462 × 16.
5. Pitfalls
- Fluid vs weight: Fluid ounces ≠ mass.
- Troy ounce: Not used here (precious metals).
- Early rounding: Keep full precision before final output.
