   SEARCH HOME Math Central Quandaries & Queries  Question from Dermot: A lawn weedkiller to be spread at the rate of 35g per Sq meter. My new spreader is calibrated in lbs per 1000 sq ft !!!! Help!! Any easy conversion method. Thanks in anticipation. Dermot. Dunshaughlin, Ireland. Dermot,

I used the calculator ability of Google on this problem.

I typed square meters to square feet into Google and the response was

1 square meter = 10.7639104 square feet.

Thus 35 g per square meter is 35/10.7639104 = 3.251606 g per square foot, which is 3251.606 g per 1000 square feet.

Then I typed 3251.606 grams to pounds into Google and the response was

3 251.606 grams = 7.16856414 pounds.

Hence 35 gm per square meter is 7.17 pounds per 1000 square feet.

Hi guys. I didn't know about that! Pretty neat. I tried it with just one query:

35 grams per square meter to pounds per 1000 square feet

and it said

(35 grams) per (square meter) = 7.16856503 pounds per (1 000 (square feet)).
