SRB propellant mass: kg and lb figures are mutually inconsistent

The Solid Rocket Boosters section states: "The rocket motors were each filled with a total 500,000 kg (1,106,640 lb) of solid rocket propellant."

These two figures do not convert to each other:

• 500,000 kg × 2.20462 lb/kg = 1,102,311 lb (not 1,106,640 lb)
• 1,106,640 lb / 2.20462 = 501,965 kg (not 500,000 kg)

The discrepancy is about 4,329 lb (roughly 1,965 kg or 0.4%). The lb figure of 1,106,640 corresponds to approximately 502,000 kg, not 500,000 kg. Either the kg value should be corrected to ~502,000 kg (to match the more precise 1,106,640 lb), or the lb value should be corrected to ~1,102,000 lb (to match the 500,000 kg round number).
