@v600@atpfm I mean for miles to kilometres, you just multiply by the golden ratio (or take the next Fibonacci number, so 5 miles ≈ 8 km; 13 mi ≈ 21 km)
There’s a reason the order is reduce, *then* reuse, *then* recycle. Not creating demand or wastage when it’s not needed is better than just giving up/in.
