Talk:Little Boy

Inconsistency: length "120 inches (300 cm)" — 120 inches = 304.8 cm, not 300 cm

The specifications box (or equivalent) states the bomb's length as 120 inches (300 cm). The inch-to-centimetre conversion is incorrect.

Verification:

120 inches × 2.54 cm/inch = 304.8 cm, not 300 cm.

Conversely, 300 cm ÷ 2.54 = 118.1 inches, not 120 inches.

For comparison, the article's other imperial-to-metric conversions are accurate:

• Diameter: 28 inches × 2.54 = 71.12 cm ≈ 71 cm ✓
• Weight: 9,700 lb ÷ 2.20462 = 4,400.6 kg ≈ 4,400 kg ✓
• U-235: 64 kg × 2.20462 = 141.1 lb ≈ 141 lb ✓

The length is the sole outlier. The correct pair is either 120 inches (305 cm) or 118 inches (300 cm).
