  1. The rounding goes to nearest 5 cents, so 2 and 7 and under round down to 0 and 5, while 3 and 8 and over round up to 5 and 10. On average in normal shopping you should end up reasonably balanced. Also as all pricing is the final price, tax inclusive most packaged, itemised things are priced in 5 cent incremental terms so no rounding needed. Only where price is for bulk items, sold by weight for example do prices calculate to non 5 cent increments. Loose items are likely sold by weight, though some cases per item, and these could have the tricky x.99 /Kg making the X factor of the cost seem cheaper than showing the real implied cost of X+1. Effectively for example fruit selling for $1.99 per Kg, appears visually cheaper than $2.00 per Kg. Irrespective of per Kg price once actual weight is applied to the goods, the end values can be anywhere from ending in 0 to 9 range these then get as above rounded up or down to nearest 5 cents. On a long supermarket, butcher , fish shop, greengrocer or anywhere multiple items are purchased by weight, number of items, the end total summation may end up with some amount of rounded. Again over all shopping you typically end up averaged in balance, in worst case only +- 2 cents. With popularity of credit or debit card purchasing, there is NO rounding applied, the actual amount to actual cents is charged. Though admittedly many supermarket for example have already rounded final total, before charging to the card, the rounded to 5 cent margin amount. By far most transactions are done in 5 cent increments, no need fir former 1 cent or pre decimal 1/2, 1 and 3 pence coins. In fact there is serious consideration to delete the 5 cent coins, for most people they just accumulate in the purse and/or coin pocket, rarely offered in cash sales, as too fiddly to count out a quantity. The traders however often are needing banks to supply 5cents coins for change they need to give, or let customers off by 5 cents and more, due to difficulty making change to a customer. My experience is many shops actually are thankful if you pay with handful of change money. Only yesterday, needing to pay a residual 65 cents, while digging for correct coins from my coin pocket I had many 5 cent coins with 10 cent also. I ended having the server grab some 45 cents in 5 cents and two 10 cent coins. He was happy for the coins. At work I often traded $1 and $2 dollar coins to the cafeteria checkout as I had too many, in exchange for $10 and $20 notes. Other times even quantities of 5, 10, 20 and 50 cent coins as well. I once had my coin pocket overloaded and had many coins also in the main jeans pocket. On clearing out and counting the coins came to over $78. That was heavy in the pockets. The way prices are going in modern times, one wonders when $5 notes get replaced by a coin.

  2. The conversion is really a simple mental arithmetic formula, absolutely accurate to all decimal places if you are bothered to do the math, but a breeze if only wanting whole degrees or if inclined to stretch it to one decimal place. Depending on direction do the following F to C ( F - 32)/9 ×5 C to F (C/5) × 9 +32 Say some one says they have a hot 35°C day. You are comfortable with Fahrenheit scale, so do the second above method, looking only for whole numbers. 35/5 = 7 then multiply by 9 , 7×9 = 63, finally add 32, 63+32 = 95°F absolute to decimal correct. How hard would be 42°C. Similarly 42/5 = 8 (ignoring decimals = 0.4) 8×9 = 72 and 72 + 32 = 104 near enough for impression, though missing something. Taking the one decimal place correctly, separately multiplying the digit and decimal place. 8.4 × 9 = 72 + 3.6 = 75.6 Then 75.6 + 32 = 107.6°F from 42°C Easy and accurate. What about F to C, let's do a easy one with least arithmetic complexity, say 50°F 50 - 32 = 18 18 / 9 = 2 2 × 5 = 10 °C How about one needing decimals, but sticking targeting whole digit value only as good enough. Say 75°F 75 - 32 = 43 43 / 9 = 4.77777 if you insist on brain exercising. But to simply mental activity, note that taking 43 up to 45, makes it easy 45 / 9 = 5 near enough right 5 × 5 = 25°C And realistically that is more than enough accuracy for most people's needs. If you are demanding and willing to do more 4.77 becomes (4 + 0.7 + 0.07) × 5 = 20 + 3.5 + 0.35 = 23.85°C None of this needs a math wizard and given a calculator so very easy even if lacking mental calculations.😊
