km/L tells you how many kilometres a vehicle travels per litre; higher is more efficient. L/100 km tells you how many litres are needed for 100 kilometres; lower is more efficient. MPG means miles per US or Imperial gallon, so the gallon type matters.
Example: 15 km/L is about 6.67 L/100 km, or 35.3 US MPG. Real-world mileage changes with traffic, tyre pressure, load, air-conditioning, route and driving style.
