Gaugewise
Not just unit conversion — what your mileage costs you this year, how it compares to going electric, and what pressure your tires should really be at. Pick a tool below.
Convert between US MPG, UK MPG, litres per 100km and km per litre instantly, with a live efficiency gauge.
Turn your fuel economy into an annual cost, a cost-per-mile figure, and a side-by-side with a typical EV.
PSI ↔ bar ↔ kPa conversion, plus a temperature-adjusted reading and general guidance by vehicle type.
Engine power and torque conversion for comparing vehicles across US and European spec sheets.
Google can already tell you that 30 MPG is 7.84 L/100km. What it can't tell you is what that actually costs you to drive this year, how that compares to switching to an EV at today's electricity prices, or what your tire pressure should read once the temperature drops. Those are the questions worth solving — so that's what these tools are built around.
