    1kg = double it and add a little lb
    1lb = just under half kg

    1cm = just under half in
    1in = a little more than double cm

    F vs C = give up

      For F and C, there’s a 10% variation from double/divide (5/9 vs 9/5).

      So add or subtract 10% after doing that part.

      F vs c is easier if you think in bands of temps. 15 C is about 60 F. Each ten degrees difference in F is about 5 degrees different in C. So 20 C is about 70 F. 10 C is about 50 F.

        I’ve worked in some capacity of manufacturing for a while now so I’ve gotten used to going back and forth. You’ll get it!
