At his last doctor visit, the doctor lowered the atenolol dose to 25mg to be taken at night due to a pulse in the 40s and my statement that my brother seemed a little slower moving. After 10 days on the reduced dose, my brother developed complete insomnia (no sleep at all for 6 nights straight).
One way to determine the GSM is to weight the towel and measure the towel length and width. Let's compare, for example, two towels both weighing 1.5 pounds (680 grams) but with different dimensions, as follows: Towel A weighs 1.5 pounds (680 grams) and measures 26 by 52 inches (.66 meters by 1.32 meters). Calculate the surface area by multiplying the length and width in meters: .66 times 1.32 equals .8712 square meters. Divide the weight in grams (680) by .8712 and find that you have a 780 GSM towel.
What Do Our Custom Spa or Hot Tub Covers Weigh? How much do your custom spa covers weigh? Depending on the model that you choose and the size of your spa, your hot tub cover will have a weight anywhere for 40-75 pounds. An example would be an 84x84 Ocean Economy spa cover with a 3 to 2 taper with one-pound foam - weighing about 40 pounds. This manageable weight allows this cover to be easily taken off by just one person.
