Is the 400000 weight unit not equals to 100kb?

100 KB is equivalent to 400000 weight units only if all inputs and outputs are legacy. A segwit transaction includes some witness data that are counted as a quarter of non-witness data.

Weight/4 = size. That is 4000000/4, making 100000 bytes which is 100kb. Or is this not correct?

Weight/4 = virtual size, not actual size.
400000 weight units is equivalent to 100 vKB.

The limit is now 400,000 weight units, not 100 KB. That's the default maximum standard transaction weight and nodes will likely reject your transaction if it has a larger weight.

Is the 400000 weight unit not equals to 100kb? I am far from my laptop now and I am not able to check somethings on my desktop Electrum right now to know how the transaction is represented, but I think it is in byte. I just noticed people do complain of kb transactions on Electrum too even while using segwit address.

The limit is 100kb, any transaction that is more than 100kb will not be broadcasted,

It may worth mentioning that the protocol allow a transaction to have larger weight and nothing prevents a miner from including a transaction with larger weight.

That's what I thought, thanks for answering my question.

In addition to what I have posted before, the transaction would be successful. Only what can make a transaction not to be successful is the transaction size limit, which is now in vsize or in weight. The limit is 100kb, any transaction that is more than 100kb will not be broadcasted, but you do not have such issue, example of people that have the issue are people that want to consolidate numerous small inputs or make transaction from coins they have collected from faucet which have numerous inputs which they may not be able to transfer until they use coin control to divided the inputs and make more than one transaction in which the transaction input size is reduced to or below 100kb per each transaction.

You have bitcoin in different addresses and you want to spend the coins on many or all addresses, your wallet can automatically do that for you. Just input the amount you want to send and it would be done.

I recently purchased the Coldcard mk4 hardware wallet and I was already familliar with electrum so I made a wallet in electrum for it and transfered my funds to the first address in the addresses tabs, I was then able to transfer bitcoin out to buy some stuff, but my question is: if I, for example, send 1 bitcoin to the first address, 1 bitcoin to the 2nd address and 1 to the third, would my coldcard automatically sweep all the coins from the address into one transaction if I had to send 3 bitcoin to someone?

Hopefully someone can answer my question, let me know if anything is unclear.
