TheSchoolRun.com closure date
As we informed you a few months ago, TheSchoolRun has had to make the difficult decision to close due to financial pressures and the company has now ceased trading. We had hoped to keep our content available through a partnership with another educational provider, but this provider has since withdrawn from the agreement.
As a result, we now have to permanently close TheSchoolRun.com. However, to give subscribers time to download any content they’d like to keep, we will keep the website open until 31st July 2025. After this date, the site will be taken down and there will be no further access to any resources. We strongly encourage you to download and save any resources you think you may want to use in the future.
In particular, we suggest downloading:
- Learning packs
- All the worksheets from the 11+ programme, if you are following this with your child
- Complete Learning Journey programmes (the packs below include all 40 worksheets for each programme)
You should already have received 16 primary school eBooks (worth £108.84) to download and keep. If you haven’t received these, please contact us at [email protected] before 31st July 2025, and we will send them to you.
We are very sorry that there is no way to continue offering access to resources and sincerely apologise for the inconvenience caused.
How do you 'convert into the same units'?

How do you 'convert into the same units'?
Children learn about measuring weight, capacity (volume of liquid) and length throughout their time at primary school.
In Year 1 they use non-standard units to compare measurements, such as measuring length with their hand spans, weighing objects on a balance in comparison to piles of blocks or using a certain cup to measure how many cupfuls of water make up the capacity of another container.
In Year 2 children start to use standard units, so grams and kilograms for weight, millilitres and litres for capacity and metres and centimetres for length.
In Year 3 children need to understand the relationship between units of measurement, so they need to know the following:
The knowledge then prepares them for being able to convert between units of measurement in Year 4 and Year 5, so if they are given the following measurements: 1400g, 600ml and 150cm they would know how to convert these into 1.4kg, 0.6 litres and 1.5m.
Converting between units of measurement in KS2
Children in upper Key Stage 2 will often need to solve word problems involving measures that require them to convert one measurement so that both measurements are in the same unit, for example:
I am 1.2m tall. My sister is 85 cm tall. How much taller am I than my sister?
Usually, a child would convert 1.2m to 120 cm and then would easily be able to work out the difference between 85cm and 120cm (which is 35cm).
In Year 6, children need to convert between units using decimals to three places, so they may come across a problem like the following:
I have 2.45 litres of orange juice. I pour 500ml of orange juice out and drink it. How much do I have left?
To work this out, it is likely a child would need to convert 2.45 litres to 2450ml, then subtract 500ml from this to make 1950ml.
In Year 6 children might also be asked to convert between imperial and metric units of measurement.
Children need a lot of practice with converting units of measurement. There can be some confusion over the fact that grams and millilitres deal in thousands and centimetres deal in hundreds. It is a really good idea for children to become confident with how many millilitres, grams and centimetres are in a litre, kilogram and metre in Year 4. (This may need lots of testing, little and often!)
