The Convert inches to cm calculator links to the BMI/BMR calculator.

As part of the older generation I find people in our generation still referring to inches as well as centimetres and metres. The reason is we grew up measuring in feet and inches, so quite a few of the measures we know by heart, such as our height or the length of a ruler, we still think of in those old imperial units rather than metric. We then need to convert those measurements to centimetres or metres.

The Convert inches to cm calculator was written to aid those wishing to convert from inches to cm (cms, centimetres, centimeters (USA spelling)), or feet and inches to cm or metres.

Secondly, since one of the first figures we need when dieting to work out our BMI/BMR is our height, I've provided a link which takes the converted result and plugs it straight into the BMI/BMR calculators I've written.

You can find the Convert inches to cm calculator at I hope you find the calculator useful.

Mapz has now been converted to use SSL encryption making it easier to use on mobile devices.

A general trend in the IT industry is a move to make the internet more secure by encrypting the connection between websites and the user's browser. This doesn't mean the sites are more secure, just that communication to and from the site is encrypted.

As this change is occurring sites which once worked OK may stop working. An example are sites such as which passes your location to the server to provide the map with information around you back to you. In the past this communication was not encrypted. Browsers such as Google Chrome and more recently Safari on macOS now require the communication to be encrypted for the site to work property.

The Mapz site provides maps for things I find useful. The nearest cinema, petrol stations and takeaway food outlets. I use the maps regularly. I wrote them for myself and make them available for others to use.

I hope you find them useful.

Woolworths petrol stations drop prices to 115.9 at some petrol stations whilst others go up to 144.9.

I was quite surprised to see Woolworths petrol drop the price for unleaded in some of their petrol stations to 115.9. Not all petrol stations as other Woolworths petrol stations are higher and some even 144.9.

The Petrol Prices Melbourne web app shows the 144.9 petrol station as dark red and the 115.9 dark green.

Right now petrol prices are going up so to see this last minute move by Woolworths to drop prices significantly was quite a surprise. Add a discount voucher and you're down to 111.9 for unleaded petrol which isn't too bad at all.

I doubt if these prices will last, or who knows how the market will respond, but whilst the prices are there, it may be worth filling or topping up.

A frustrating couple of weeks with sites using SSL.

My apologies to those who haven't been able to use the sites,, and

Whilst there was a problem lurking in the hosting company's service since mid December, on Saturday the proverbial hit the fan and my sites started to not work. "Not happy Jan!"

All has been fixed and the sites are now working as expect.

Apologies again but this is the type of thing we are all faced with in IT. Certainly feels good to have the problem fixed.

Some VentraIP sites using Let's Encrypt currently have problems.

If you're trying to access the Petrol Prices Melbourne, Nearest Petrol Station, or the Speed Camera Locations sites, there is currently an issue with the hosting service VentraIP.

For a few weeks now VentraIP's implementation of Let's Encrypt has been giving problems. This started a few weeks ago with not being able to enable SSL for one site and yesterday, the problem became worse with three sites mentioned above that have SSL enabled, are now showing has having certificate problems.

You can still access the sites if you use Safari on the Mac, or Internet Explorer/Edge on Windows and select continue when given the certificate warning. However this will be disconcerting to people who don't know what's happening. Mobile users however will probably be out of luck.

My apologies for any inconvenience. VentraIP are working on the problem and hopefully it will be resolved in a timely manner.

Update: 11 January 2017
Certainly a frustrating time. Thanks to the team at VentraIP for sorting this out.

Next petrol price hike is going to surprise people

For the last few weeks I've not quite understood why the retail price of petrol has come down so slowly. Since the last price hike for Melbourne, which occurred on the 9th of November, 58 days ago, prices have come down 8 cents or 0.13 cents per day. In the past I've prices have typically dropped between 0.5 to 1 cent per day and the petrol price cycle being around 3-4 weeks.

Initially I thought this was because the petrol companies kept prices high for the Christmas holiday period. Since people are used to the high price there would be no outcry with the petrol companies profiteering at holiday times and thus the bad press. However this doesn't appear to be the case.

What has also been happening is in the background the wholesale price has been going up. On the 9th of November the average wholesale price was 108.3, and today (6 January 2017), the average wholesale price is 118.9.

So perhaps there's two situations that have occurred. Keeping prices high to avoid bad press, but also increasing wholesale prices.

In the near future we are probably going to see the highest petrol prices we've seen for some time. When the petrol price discounting cycle finishes and the restoration to the higher price occurs, we often see a 20-30 cent increase. I suspect the next price increase will take us up to 139.9 (but could be 144.9)  and that will probably occur within the next one to two weeks.

When the price restoration (or what I call the petrol price hike) occurs, I will as usual alert everyone using this blog, Google+, Twitter and my Facebook account. You can also keep an eye on where I publish prices for petrol stations in my area.

Electricity price increases occur around this time of the year.

In January the new prices for electricity generally start to apply. In my case the new prices kicked in on the 7th of December.

For those interested in checking how much the new rates will affect their electricity bill I created a video ( showing how to use the Cheapest Electricity Provider web app to see how much your bill will increase by and by what percentage.

If you're thinking about changing electricity providers, the Cheapest Electricity Provider web app may be able to assist you in comparing rates.

Our rate is going up 12.5%, or about $80 a year. Whilst this is a considerable increase I've done a quick check around and since other providers are also increasing their rates, I haven't yet found a better rate worth the time to change to. Hopefully you have better luck.

Police checking cars for speeding on Reynolds Road Templestowe at bottom of hill.

Yesterday I went for a bike ride and noticed a policeman standing behind a police car with a speed gun. They were parked at the bus stop on Reynolds Road near Blackburn Road Templestowe.

The problem I see with this approach is the police were checking speeding drivers on a very hilly road at the bottom of a long hill. A spot that would be incredibly easy for people to exceed the speed limit by a small amount for a short period of time.

I can't help feeling this form of policing our roads won't be well accepted by the general public.

I recall a time when it was suggested people weren't booked in such places (going down hills) but it appears those times have passed.
