3 English/Metric Gas Flow Rate Conversion Chart Conversion Formulas: cfh x .472195 = L/min L/min x 2.12 = cfh Find the flow rate to be converted in the center column. If in cfh, read L/ min in column to right. If in L/min, read cfh in column to left. cfh L/min 2.12 1 0.472 4.24 2 0.944 6.36 3 1.416 8.48 4 1.888 10.60 5 2.360 12.72 6 2.832 14.84 7 3.304 16.96 8 3.776 19.08 9 4.248 21.20 10 4.719 23.32 11 5.191 25.44 12 5.664 27.56 13 6.135 29.68 14 6.607 31.80 15 7.079 33.92 16 7.551 36.04 17 8.023 38.16 18 8.495 40.28 19 8.967 42.40 20 9.439 44.52 21 9.911 46.64 22 10.383 48.76 23 10.855 50.88 24 11.327 53.00 25 11.799 55.12 26 12.271 57.24 27 12.743 59.36 28 13.215 61.48 29 13.686 63.60 30 14.158 65.72 31 14.631 67.84 32 15.102 69.96 33 15.574 72.08 34 16.046 44.20 35 16.518 76.32 36 16.990 78.44 37 17.462 80.56 38 17.934 82.68 39 18.406 84.80 40 18.878 86.92 41 19.350 89.04 42 19.822 91.16 43 20.294 93.28 44 20.766 95.40 45 21.238 97.52 46 21.710 99.64 47 22.182 101.76 48 22.653 103.88 49 23.125 106.00 50 23.597 108.12 51 24.069 110.24 52 24.541 112.36 53 25.013 114.48 54 25.485 116.60 55 25.957 118.72 56 26.429 120.84 57 26.901 122.96 58 27.373 125.08 59 27.845 127.20 60 28.317 129.32 61 28.789 131.44 62 29.261 133.56 63 29.733 135.68 64 30.205 137.80 65 30.677 139.92 66 31.149 142.04 67 31.621 144.16 68 32.097 146.28 69 32.564 148.40 70 33.036 150.52 71 33.508 152.64 72 33.980 154.76 73 34.452 156.88 74 34.924 159.00 75 35.396 161.12 76 35.868 163.24 77 36.340 165.36 78 36.812 167.48 79 37.284 169.60 80 37.756 171.72 81 38.228 173.84 82 38.700 175.96 83 39.172 178.08 84 39.644 180.20 85 40.116 182.32 86 40.587 184.44 87 41.060 186.56 88 41.532 188.68 89 42.003 190.80 90 42.475 192.92 91 42.947 195.04 92 43.419 197.16 93 43.891 199.28 94 44.363 201.40 95 44.835 203.52 96 45.307 205.64 97 45.778 207.76 98 46.251 209.88 99 46.723 212.00 100 47.195 cfh L/min cfh L/min cfh L/min cfh L/min
