Grams to Yards Yarn Calculator

When starting a knitting or crochet project, one of the most common questions is simple: How many yards do I get from this much yarn? Yarn is often sold by weight (grams), but patterns usually require yardage. Converting between the two ensures you buy enough without overspending.

The Core Formula Behind the Calculator

Every yarn label provides a clue. It typically lists the length per 100 grams.

Main Formula
Yards = (Grams × Length per 100g) ÷ 100
*Where Length is in meters

If the length is given in meters, convert to yards:

Meter to Yard Conversion
1 meter = 1.09361 yards
*So: Yards = Meters × 1.09361

Worked Example

Suppose you have 150 grams of yarn labeled 240 meters per 100g.

Step 1: Calculate meters
(150 × 240) ÷ 100 = 360 meters

Step 2: Convert to yards
360 × 1.09361 ≈ 394 yards

So, 150 grams gives you about 394 yards.

Reverse Formula (Yards to Grams)

If you need to find out how much yarn to buy:

Reverse Calculation
Grams = (Yards × 100) ÷ Length per 100g
