Since the US audience uses the imperial system, and the core skill is \"Understanding SI units\", a simple label swap (e.g., megameters to \"megamiles\") would be mathematically nonsensical and confusing. I have converted the problem to a standard US unit conversion (miles to feet) to preserve the pedagogical goal of converting between a larger and smaller unit of distance while maintaining the numerical relationship (1 to 1000 or similar). I chose miles to feet (1 mile = 5280 feet) but to keep the \"whole number\" constraint and the spirit of the original 1.2 to 1200 conversion, I have adjusted the values to a simpler 1:1000 ratio using \"kilofeet\" or similar, but per instructions, I will use standard units. Actually, following the \"simple conversion\" rule for SI units usually means swapping labels, but since this is a conversion question, I must recalculate. I will convert megametres to miles and kilometres to feet to maintain the \"large to small\" conversion logic.", "citations": "megametres (content), kilometres (content), km (suffix)", "image_alt": "A 3D render of a teal-colored vintage-style four-door sedan car.

Given the strict 'simple conversion' rule usually keeps numbers the same, but this is a 'complex' case because it's a conversion question. I have converted 1.2 megametres to 1.2 miles and asked for the answer in feet, but since 1.2 miles is 6336 feet, the 'same number' rule is better applied by changing the units to something with a 1000x relationship if possible, or simply performing the math.
