Multiply a mileage figure by 1.60934 to get the exact kilometer figure, then round the way owner's manuals typically do: a 5,000-mile interval is stated as about 8,000 km, 10,000 miles as about 16,000 km, and so on. Common US intervals convert as follows: 3,000 mi = about 4,828 km (rounded to 5,000 km); 7,500 mi = about 12,070 km (rounded to 12,000 km); 15,000 mi = about 24,140 km (rounded to 24,000 km); 30,000 mi = about 48,280 km (rounded to 48,000 km); 60,000 mi = about 96,560 km (rounded to 96,000 km); 100,000 mi = about 160,934 km (rounded to 160,000 km).
A converted figure is not always the same interval a non-US market's manual prints, because manufacturers publish market-specific schedules driven by local fuel quality, typical driving conditions, and time-based warranty or regulatory limits that can differ by market. If a car was sold new outside the US, the reliable interval is the one in its own owner's manual or maintenance minder, not a converted US number - this page is a translation tool, not a replacement for that manual. When tracking odometer readings, keep to one unit consistently rather than mixing km and mile entries in the same log.
