Q: On the other hand, to convert a Fahrenheit temperature to a Kelvin temperature, it’s easiest to convert to Celsius and then make the conversion to Kelvin from there. This means we begin by subtracting 32.  Let’s say the temperature is 82°F. Subtract 32 from that number. 82 - 32 = 50. When converting Fahrenheit to Celsius, the next step is to multiply by 5/9–or divide by 1.8 if you have a calculator around. 50 x 5/9 = 27.7, which is the Fahrenheit temperature now converted to Celsius. Since the difference between Celsius and Kelvin = 273.15, you can then get the Kelvin temperature by adding 273.15.  273.15 + 27.7 = 300.8. Therefore, 82°F = 300.8K. Compare your result to this table to see if it makes sense. If it doesn't seem to fit the scale, try again. Make sure you subtract before multiplying.   ºFahrenheit kelvins (approx)    -25    241     0    255     32    273.15 exactly     70    294     100    311     150    339     212    373.15 exactly
A: Subtract 32 from the Fahrenheit temperature. Multiply that number by 5/9. Add 273.15 to this number. Check your answer.

Q: In order for you to know how well you like a mattress, you must test it out in the store. Search around looking for mattresses that meet your criteria, and then lay on each to see how you like them.  Lay on each mattress for at least 2-3 minutes, and up to 15. The floor models are out specifically for this reason, so don’t be hesitant to lay in the store for a bit. Ignore descriptors on tags such as “ultra plush,” “super soft,” or “extra firm.” These aren’t regulated terms and are used freely within each mattress brand without consistency between them. Instead, just lay on the mattress to get a feel for how soft or firm it is. Try a firm, a plush, and a pillow-top mattress to get a feel for which type you prefer. Compare these types all within the same mattress brand to get the most accurate idea of which you like best. Ask to see a cutaway of the mattress if it’s available, so you can see exactly what it is you may be sleeping on. A comfort guarantee varies between brands, but is a certain period of time after you’ve purchased your mattress in which you can return or exchange it for free.  Always do this before you purchase and verify at purchase to make sure you are getting the correct information. Find out how long the comfort guarantee lasts for, as this can be different depending on each brand. Learn if you must pay for shipping to/from your home if the mattress doesn’t work out for you. This way you won’t be surprised by extra costs later. Many mattress brands and stores allow you to test the mattress in your home for up to thirty days. If you can, take this opportunity to verify that this mattress meets your sleep needs. Make sure that the mattress you are purchasing offers a minimum ten year, non-prorated warranty. Although buying just a mattress is all that seems necessary, you must also purchase a minimum of a box spring to support it as well.  Always buy a new box spring with your new mattress, as old box springs wear out over time and lose the desired support and firmness. Purchase a waterproof mattress protector to cover your new mattress. This not only makes cleanup easier should something spill on it, but will keep the warranty intact. Many warranties void out if the mattress is stained or spilled on. The prices of mattresses can often be lowered with a little bartering done with a sales associate or store manager. Use the numbers you found online earlier to determine if you are getting a good deal.  Include the cost of old mattress pick-up and the delivery and setup of the new mattress in the total cost. Ask for freebies; many stores will throw in free services if they are simply asked.
A: Test out mattresses. Ask about a comfort guarantee. Take it for a trial run. Check the warranty. Purchase the necessary mattress add-ons. Negotiate the price.

Q: Here, their juicy insides will continue to cook without getting dried out or burnt. Use the full surface of the low-heat side of your grill to keep the burgers from touching one another.  Flip the burgers at about the 2-minute mark. This will ensure that all of the patties are evenly cooked through on both sides.
A: Cook the burgers for 3-4 minutes on the low-heat side.

Q: Brushing your teeth in the morning and the evening can help to reduce plaque and prevent cavities. Make sure that you use a fluoride toothpaste to brush your teeth and take your time as well. Other good brushing habits include:  Brush all surfaces of your teeth (front, back, tops, and along the gumline). Keep your toothbrush in a stand that allows it to air dry (a moist toothbrush is more prove to bacteria). Replace your toothbrush every three to four months. Flossing is also crucial because a toothbrush cannot reach between your teeth. You can use regular dental floss or pre-threaded flossers to get in between your teeth. When you floss, you should also make sure to:  Use a long (18”) piece of floss so that you will have enough to floss between all of your teeth. Run the floss up and down the sides of your teeth. Do not just pull the floss in and out between your teeth. Use a gentle touch. Pressing too hard may cause injury or bleeding to your gums. Swishing with an antimicrobial mouthwash or a mouthwash that contains fluoride may also help to improve your dental health. Look for a mouthwash that fights plaque and use it after brushing and flossing for extra protection. Regular checkups can help your dentist to detect any problems, such as tooth decay or plaque build-up. Your dentist can provide treatments to help promote your dental health and fix problems before they get worse. Make sure that you see your dentist twice per year for a cleaning and exam. Also call your dentist if you notice any signs of a problem such as:  red, bleeding gums gums that are pulling away from your teeth changes in the alignment of your teeth loose teeth sensitivity to hot and cold constant bad breath or a bad taste in your mouth
A:
Brush your teeth twice per day. Floss your teeth twice daily. Swish with mouthwash after brushing and flossing. Schedule regular checkups with your dentist.
