Converting to and from metrics

Here are a few quick conversions that you may need from time to time. These are approximations, but they’re much easier to do in your head and close enough for your crocheting needs!

Yards and meters

  • A yard is 36 inches
  • A meter is 39 inches
  • Multiply yards by 90 percent (0.9) to get meters (100 yds = 90 m)
  • Multiply meters by 110 percent (1.1) to get yards (100 m = 110 yds)

Inches and centimeters

  • 2.5 is the magic number here
  • Multiply inches by 2.5 to get centimeters: 4 in. x 2.5 = 10 cm
  • Divide centimeters by 2.5 to get inches: 10 cm ÷ 2.5 = 4 in.

Ounces and grams

50 g = 1.75 oz.; 100 g = 3.5 oz
